Title 1:

When Free-Space Optical Communications Meets Unmanned Aerial Vehicles

Date and Time:

13:30-15:00, May 14th, 2019

Location:

ROOM 1013, BUILDING 2A, NO.2 YIKUANG STREET,

HARBIN, HEILONGJIANG, CHINA

Abstract:

The fifth-generation (5G) wireless network is expected to leap ahead of current wireless technologies by offering a variety of remarkable services, and it will pave the way for new types of data-hungry applications. To reach this milestone, it is necessary to enhance the network capacity through an ultra-dense deployment of low-power and low-cost remote radio heads (RRHs). However, due to the RF spectrum scarcity, the data explosion challenge triggered by such data-rate-hungry services cannot be well addressed by using RF-based networks alone.  Optical fibers have so far been considered as a high capacity solution for establishing front-haul links while network operators have to seek municipal approval for digging up a street to lay its cable. However, because of cell densification as well as the wide deployment of RRHs in 5G, the number of existing fiber links used for a front-haul connection is limited. To cope with these challenges, the idea of employing free space optical (FSO) communication has been recently proposed for establishing back-haul and front-haul links as an alternative easy-to-deploy solution to traditional optical fiber communication. Indeed, recent advances in small-scale unmanned aerial vehicles (UAVs) has opened up new horizons for establishing UAV-FSO links. In this talk, a state-of-the-art literature review on UAV-based FSO communications is provided. Moreover, the technical challenges of establishing UAV-based FSO links as well as the proposed solution to confront such challenges are expressed in details.

 

Title 2:

80 Years of Research on Sum of Lognormal Random Variables: Recent Breakthroughs and Applications in Wireless Communications

Date and Time:

15:15-16:45, May 14th, 2019

Location:

ROOM 1013, BUILDING 2A, NO.2 YIKUANG STREET,

HARBIN, HEILONGJIANG, CHINA

Abstract:

The distribution for the sum of lognormal random variables finds applications in many science and engineering disciplines, and it is particularly important for wireless communication engineers. However, the distribution for the simplistic sum of independent lognormal random variables is analytically intractable, and it is more so for a sum of correlated lognormal random variables with non-identical parameters. In 1934, Wilkinson from Bell Telephone Labs first studied this problem in an unpublished work. Since then, various approximations have been proposed in the literature. All these approximations fail to accurately quantify the left tail (or right tail) behavior of the distribution function of a sum of lognormal random variables. In this talk, in the context of diversity receptions over lognormal fading channels, we first present that the left tail distribution of the sum of independent lognormal random variables can be accurately represented by a Marcum Q-function. The proposed analytical result outperforms all existing well-known sum of lognormal approximations. Using a different approach, we then extend the problem to a sum of correlated and non-identically lognormal random variables, and show that its left-tail distribution can again be represented by another Marcum Q-function. Our study reveals a number of new and surprising engineering insights into the transmission characteristics over the lognormal fading channels. For example, for the dual-branch case, we show that the outage performance of negatively correlated lognormal channels is better than that of independent lognormal channels. We also show that under certain parameter conditions, one of the two lognormal channels can contribute no performance gain to the diversity reception systems. This implies that one link can be discarded without causing asymptotic performance loss. These new findings can guide the communication engineers to design better systems for transmission over the lognormal fading channels.

 

Title 3:

Multiple Scattering Models for Scattering Based Optical Wireless Communication

Date and Time:

8:30-10:00, May 16th, 2019

Location:

ROOM 1013, BUILDING 2A, NO.2 YIKUANG STREET,

HARBIN, HEILONGJIANG, CHINA

Abstract:

Scattering based optical wireless communications, e.g., ultraviolet communication and underwater optical communication, have attracted increasing attention for their valuable military and civil implementations. Multiple scattering effects have to be considered in accurate channel path loss and impulse response estimations. By now, the Monte-Carlo method based channel models are used for modeling the multiple scattering channel in both ultraviolet communication and underwater optical communication. This presentation focuses on a special Monte-Carlo model: the Monte-Carlo integration (MCI) model. We proved the feasibility of obtaining system impulse response function by MCI model for the first time. After analyzing the convergence performance of the MCI model, we proposed an improved MCI model based on the partial importance sampling method (MCI-PIS model). Numerical simulation for the computation efficiency of different Monte-Carlo models suggests that for a three-order scattering case, the computation efficiency of the MCI-PIS model is about 12 times of the original Monte-Carlo integration model based on uniform sampling (MCI-US model) and 5.6 times of the widely used Monte-Carlo simulation (MCS) model for ultraviolet communication, and 10.6 times and 2.12 times of those for the underwater optical communication. The numerical results also suggest that the computation efficiency of the MCI-PIS model can be higher in a higher scattering order communication compared to the MCS model. We provided a new optimizing direction for the improvement of Monte-Carlo channel models for the scattering based optical communications.

 

Title 4:

How to Write an IEEE Style Paper and Get it Published?

Date and Time:

10:15-11:45, May 16th, 2019

Location:

ROOM 1013, BUILDING 2A, NO.2 YIKUANG STREET,

HARBIN, HEILONGJIANG, CHINA

Abstract:

Institute of Electrical and Electronics Engineers (IEEE) is world’s largest professional association which is best known, among other engineering disciplines, for its high quality flagship journal and conference publications. For electrical engineering graduate students and researchers, it is increasingly important to publish their research findings in core IEEE journals and conferences. However, most top IEEE journals and conferences typically have acceptance rate at 35% or much less, and it is also rare that a manuscript receives an outright acceptance. In this talk, I will introduce basic elements of an IEEE style paper, and offer some personal tips and strategies on how to improve the odds of acceptance. The goal of this presentation is to provide the proper guidance to the beginning graduate students so that, with some practice, they can write an IEEE style paper with high confidence. These graduate students can then focus more on the technical contributions of their work.

Title 1: Introduction to Frequency Domain Turbo Equalization and its Applications

Date and Time: 9:00-11:30, September 22, 2018

Location:ROOM 1011, BUILDING 2A, NO.2 YIKUANG STREET,

HARBIN, HEILONGJIANG, CHINA

Abstract:

The goal of this lecture is to provide the audience with understanding of “turbo principle”.  To achieve this goal, this lecture will be started with the sliding window soft cancellation minimum mean squared error filtering (SC-MMSE) turbo equalization for single carrier signal transmission over frequency selective fading channels with relatively short memory. Then, this lecture introduces time-domain block-wise processing, and shows that no gains achieved by making modifications from sliding window to block wise processing due to its intractably heavy computational complexity.  Plus, this lecture further modifies the time-domain block wise SC-MMSE turbo equalization to frequency domain (FD SC-MMSE), where it is shown that the required computational complexity is very light and is constant regardless of the channel memory length.

Also, this lecture provides introductory explanations to the extrinsic information transfer (EXIT) chart as a tool for evaluating the efficiency of mutual information exchange. Information theoretic convergence analysis of the FD-SC MMSE turbo equalization, exemplifying the turbo principle, are provided in this lecture Furthermore, the concept of the FD SC-MMSE turbo equalization is applied to multiple input multiple output (MIMO) systems as a reasonable extension of the technique.  It is shown that when analyzing the mutual information exchange for MIMO turbo equalization, multi-dimensional EXIT plane has to be used.  Finally, trends and future prospects of research work towards broadband mobile communication systems are introduced, including turbo equalization of orthogonal frequency division multiplexing (OFDM) and single carrier (SC)-FDMA as well as the technique for eliminating the cyclic prefix (CP) from block-wise processing based FD SC-MMSE turbo equalization.

 

Title 2: Turbo Equalization and its Information Theoretic Analysis

Date and Time: 18:00-20:30, September 25, 2018

Location:ROOM 1011, BUILDING 2A, NO.2 YIKUANG STREET,

HARBIN, HEILONGJIANG, CHINA

Abstract:

A goal of this talk is to provide audience with the knowledge about the relationship between relay systems and the Distributed Coding techniques for correlated sources. To achieve this goal, this lecture is started by the re-enforcement of understanding of turbo principle, especially, frequency-domain soft cancellation minimum mean square error (FD SC-MMSE) based multiple-input multiple-output (MIMO) turbo equalization (This part is provided in Lecture-1). This lecture uses a lot of multi-dimensional extrinsic information transfer (EXIT) analysis to reveal the convergence properties of the FD SC-MMSE MIMO equalization, and identifies the optimal, close capacity achieving structure. It is shown that even with very simple serially concatenated convolution code with the component codes being very simple memory one codes can achieve near-capacity performance. Furthermore, the inner code, which is a very simple memory one recursive code, can eliminate the error floor due to the intersection of the EXIT curves, resulting in very sharp shape of the turbo cliff. This lecture also makes comparison of the shape of the EXIT curves with recursive and non-recursive convolutional codes.

At the final part of this lecture, we intentional “add” binary errors randomly between the MIMO antennas, and analyses the impacts of the “artificial errors”. It is shown that if the FD SC MMSE equalizer can utilize the error probability to modify the log likelihood ratio (LLR) in the vertical iteration, we can eliminate the effect of the “artificial errors”. The “artificial error” probability can be estimated only at the decoder side (no side information needed).

Obviously the “artificial errors” inserted in the connections between the antennas correspond to the “intra-link” errors in distributed lossy forwarding cooperative networks. Therefore, the last part of this lecture is a preparation of Lecture 3, Tutorial on Lossy Forward Relaying: Orthogonal and non-Orthogonal cases.

Title 1: Efficient Decoding over Unknown Impulsive Noise Channels

Date and Time: 10:00-11:30, September 2, 2018

Location:ROOM 1011, BUILDING 2A, NO.2 YIKUANG STREET,

HARBIN, HEILONGJIANG, CHINA

Abstract:

It has been known from many researches that communication systems are susceptible to memoryless impulsive noise characterized by, for instance, the Bernoulli-Gaussian model. In order to combat this obstacle, channel coding has long served as an effective tool, especially in the context of moderately frequent occurrence of impulses, when the statistics of impulsive noise can be realized at the decoder. In this talk, irrespective of the statistics of impulses, an efficient decoding scheme is introduced by incorporating clipping-featured technique into the Viterbi algorithm. As a result, the proposed decoding scheme, while having a complexity at the same order as that of the Viterbi algorithm, is on a par with its optimal counterpart, for which statistics of impulses is assumed known at receiver, in terms of bit error probability. In addition, the Chernoff bounds of the bit error probabilities of the devised decoding algorithm are derived for both Bernoulli-Gaussian noise model and Middleton Class-A noise model. Comparisons between the bounds we derived and the simulated error rates under a variety of settings indicate that the ensuing analysis can provide critical insights for the efficacy of the proposed decoding approach when dealing with precarious frequent strong impulses.

 

Title 2: Novel FFT over Binary Finite Fields and Its Application to Reed-Solomon Erasure Codes

Date and Time: 10:00-11:30, September 7, 2018

Location:ROOM 1011, BUILDING 2A, NO.2 YIKUANG STREET,

HARBIN, HEILONGJIANG, CHINA

Abstract:

Abstract A fundamental issue in algebra is to reduce the computational complexities of arithmetic operations over polynomials. Many fast polynomialrelated algorithms, such as encoding/decoding of Reed-Solomon codes, are based on fast Fourier transforms (FFT). However, it is algorithmically harder as the traditional fast Fourier transform (FFT) cannot be applied directly over characteristic-2 finite fields. To the best of our knowledge, no existing algorithm for characteristic-2 finite field FFT/polynomial multiplication has provably achieved O(h log2(h)) operations. In this talk, we present a new basis of polynomial over finite fields of characteristic-2 and then apply it to the encoding/decoding of Reed-Solomon erasure codes. The proposed polynomial basis allows that h-point polynomial evaluation can be computed in O(h log2(h)) finite field operations with small leading constant. As compared with the canonical polynomial basis, the proposed basis improves the arithmetic complexity of addition, multiplication, and the determination of polynomial degree from O(h log2(h) log2 log2(h)) to O(h log2(h)). Based on this basis, we then develop the encoding and erasure decoding algorithms for the (n = 2r; k) Reed-Solomon codes. Thanks to the efficiency of transform based on the polynomial basis, the encoding can be completed in O(n log2(k)) finite field operations, and the erasure decoding in O(n log2(n)) finite field operations. To the best of our knowledge, this is the first approach supporting Reed-Solomon erasure codes over characteristic-2 finite fields while achieving a complexity of O(n log2(n)), in both additive and multiplicative complexities. As the complexity of leading factor is small, the algorithms are advantageous in practical applications.

This work was presented at the 55th Annual Symposium on Foundations of Computer Science (FOCS 2014).

IEEE Communications Society has 4 regions and 25,600 members currently in the world. China belongs to the Asia-Pacific, which includes 6 chapters.As the youngest one, IEEE ComSoc Harbin Chapter contains 147 members from universities and institutions in three provinces of Northeast China. The chapter is a non-profit academic organization aiming to lead the professional career of members, provide academic exchange platforms and service channels for members so as to promote the development of communication theory, technology and industry.

Harbin Chapter was founded by Prof. Weixiao Meng in 2012, who was also the chair. Associate Prof. Shuai Han served as the vice chair and established the student chair. In the past 6 years, Harbin Chapter has made outstanding achievements in academic exchanges, membership services, upgrades, development, information consultation and won consistent commendation from IEEE Communications Society. This is the first time for Chinese academic organizations to win the serialization of international academic activities award. Prof. Weixiao Meng attended the conference,accepted the award from the international academic organization and made a speech.

In the past one year, IEEE ComSoc Harbin Chapter tried its best to attract more elites and promote quantity and quality of its membership. In order to enrich the chapter   and elevate its international influence, Harbin Chapter organized a series of recruiting events facing to faculties and students of northeastern universities in China which has relative great influence.

The core volunteers has made a lot of effort to enhance the IEEE and ComSoc. Chapter Chair, Prof. Weixiao Meng and Vice Chair, Dr. Shuai Han organized a publicity meeting where they described the history, development and current influence of the IEEE ComSoc Harbin Chapter in details, which have become one of routine activities for newcomers every September. Prof. Weixiao Meng kept contacting with all the EEE and ECE Deans of universities from three provinces of Northeast China, encouraged them to distribute the recruiting polices to the corresponding areas of their own universities. Faculty members also shared the functions of IEEE ComSoc with their students and inspired them to start their professional careers with ComSoc student members. At the same time, Harbin Chapter noticed the crutial state of multimedia, so it made full use of social networks for more sufficient propaganda. After contacting with professors who are focusing on information and communications engineering in northeastern universities, QQ ,WeChat and other social communication groups which mainly oriented to teachers, master and Ph.D students were established among universities and various organizations. IEEE ComSoc Harbin Chapter nominated Ms. Qian Chen, a Ph.D student member as the student chair, who plays an important bridge role between chapter and all kinds of students in March, 2018.In those groups, Harbin Chapter issued the relevant notifications for the recruiting events and sent warm invitations to the potential teachers and students. In order to organize some activities afterward convieniently, Harbin Chapter raised funds to customize T-shirts for the new members and guests, and mailed them to everyone, which were extremely popular among them. Since most of students had no VISA/MASTER cards, the payment of membership became knotty. A faculty member was willing to pay equivalent dollars online for new student members so that the problem was succesfully solved. From these details, therefore, newcomers increased their confidence to Harbin Chapter.

Due to meticulously preparation, many teachers and students responded positively. In order to remain its lasting competitiveness, Harbin Chapter held more than 10 visiting academic lectures last year and hosted 3 DLT and DLS in recent years. In addition, they drafted newsletters to ComSoc twice a year. Their Monday Seminar is still ongoing chairing by student members in Harbin once a week.

Thanks to IEEE Communications Society for confirming the achievements of IEEE Comsoc Harbin Chapter in the last year and awarding the three awards for it. Harbin Chapter will keep seriousness, pragmatic and innovation, try to make greater effort for advanced contributions to IEEE Communications Society in the future.

HIT SEIE Summer Academic Activities VI: Invited Talk by Prof. Lingyang Song

Title:Game theory for Big Data Processing

Date and Time: 11:30—13:00, Auguest 8, 2017

Location:ROOM 1013, BUILDING 2A, NO.2 YIKUANG STREET,

HARBIN, HEILONGJIANG, CHINA

Abstract: Modern communication networks are becoming highly virtualized with two-layer hierarchies, in which controllers at the upper layer with tasks to achieve ask a large number of agents at the lower layer to help realize big data processing. In this talk, we combine optimization approaches and game theory to address the tradeoff and convergence issues for incentive mechanism design in hierarchies. Specifically, we propose a multiple-leader multiple-follower (MLMF) game-based alternating direction method of multipliers (ADMM) that incentivizes the agents to perform the controllers’ tasks in order to satisfy the corresponding objectives for both controllers and agents. Both analytical and simulation results verify that the proposed method reaches a hierarchical social optimum and converges at a linear speed. More importantly, the convergence rate is independent of the network size, which indicates that the MLMF game-based ADMM can be used in a network with a very large size for big data processing.

Title:The Deep Learning Vision for Heterogeneous Network Traffic Control: Proposal, Challenges, and Future Perspective

Date and Time: 10:00—11:30, Auguest 8, 2017

Location:ROOM 1013, BUILDING 2A, NO.2 YIKUANG STREET,

HARBIN, HEILONGJIANG, CHINA

Abstract:

Recently, deep learning, an emerging machine learning technique, is garnering a lot of research attention in several computer science areas. However, to the best of our knowledge, its application to improve heterogeneous network traffic control which is an important and challenging area for IoT by its own merit has yet to appear because of the difficult challenge in characterizing the appropriate input and output patterns for a deep learning system to correctly reflect the highly dynamic nature of large-scale heterogeneous networks. In this talk, an appropriate input and output characterizations of heterogeneous network traffic will be introduced and a supervised deep neural network system will be proposed. I will describe how our proposed system works and how it differs from traditional neural networks. Also, preliminary results will be discussed and I will demonstrate the encouraging performance of our proposed deep learning system compared to a benchmark routing strategy (Open Shortest Path First (OSPF)) in terms of significantly better signaling overhead, throughput, and delay.

Abstract:Modern society depends on faster, safer, and environment friendly transportation system. Vehicular communications network in terms of vehicle to vehicle, vehicle to infrastructure, vehicle to pedestrian, vehicle to cloud, and vehicle to sensor, provides a solution to modern transportation. In this talk, we first introduce the all connected vehicles. We then present the challenges and scientific research issues. of vehicular communications network. As examples, we show how to utilize mobility characteristics of vehicles to derive the achievable asymptotic throughput capacity in VANETs, and how to develop the charging strategies based on mobility of electric vehicles to improve the electricity utility, in order to approach load capacities of charging stations in VANET-enhanced smart grid. We conclude the talk by discuss the future autonomous driving.
