Title: Feedback in Wireless Networks: Recent Results & Discoveries


Abstract: Although Shannon’s work showed that feedback does not increase capacity in point-to-point communications, it is known to be quite useful in multi-terminal systems. Notably, feedback has long played a major role in the development of wireless networks, from its earliest and simplest uses in protocols such as Aloha, to its more sophisticated uses in advanced multiple-antenna systems. Recent years have seen a considerable research effort in this area, both on the practical uses of feedback and on the fundamental, and sometimes surprising, properties that it can impart to networks. This talk will review some of the latter developments, notably as they relate to the capacities of interference, broadcast and time-varying channels.

Title: Advanced Spatial Modulation Techniques for MIMO Systems


Abstract: The use of multiple antennas at both transmitter and receiver sides has been shown to be an effective way to improve the capacity and reliability of single antenna wireless systems.  A novel concept known as spatial modulation (SM) has been introduced recently as an alternative to these two MIMO transmission techniques. In this presentation, after a brief introduction of SM, first the performance of SM is presented. Then, a new MIMO transmission scheme, called space-time-block coded spatial modulation (STBC-SM) is introduced and its design and performance issues are discussed.

Title: Design and Analysis of Coded Slotted Aloha (CSA) Scheme for Erasure Channels

: For the future machine-to-machine communications (M2M), efficient random multiple access protocols are required to accommodate a massive number of uncoordinated transmissions. 
It is known that packet contention is a critical issue for increasing the throughput in the uncoordinated transmissions. Thus, how to deal with packet contentions is the key for novel efficient multiple access schemes of future wireless communication networks. In this talk, we investigate the design and analysis of random multiple access schemes and coding techniques for the future machine to machine. We design the optimal coded slotted Aloha (CSA) scheme with repetition codes and maximum distance separable (MDS) codes under both packet erasure channels and slot erasure channels. We derive an upper bound on the throughput of CSA scheme. We show that our optimal distributions improve the maximum traffic load and enhance the throughput of the CSA scheme significantly. Moreover, we propose a Gaussian elimination (GE) aided successive interference cancellation (SIC) decoding (GE-SIC) method to further improve the throughput of the CSA scheme. We demonstrate that by introducing the GE decoding to recover packets that cannot be decoded by the SIC decoding, the peak throughput of CSA scheme can reach as high as 90%.

Title: A Non-Stationary IMT-A MIMO Channel Model for High Mobility Systems


Abstract: With the recent developments of high-mobility wireless communication systems, e.g., high-speed train (HST) and vehicle-to-vehicle (V2V) communication systems, the ability of conventional stationary channel models to mimic the underlying channel characteristics has widely been challenged. Measurements have demonstrated that the current standardized channel models, like IMT-Advanced (IMT-A) and WINNER II multiple-input multiple-output (MIMO) channel models, offer stationary intervals that are noticeably longer than those in measured HST channels. In this talk, we propose a non-stationary IMT-A channel model with time-varying parameters including the number of clusters, powers and delays of clusters, angles of departure (AoDs), and angles of arrival (AoAs). Based on the proposed non-stationary IMT-A channel model, important statistical properties such as the local spatial cross-correlation function (CCF) and local temporal autocorrelation function (ACF) are derived and analyzed. Simulation results demonstrate that the statistical properties vary with time due to the non-stationarity of the proposed channel model. An excellent agreement is achieved between the stationary interval of the developed non-stationary IMT-A channel model and that of relevant HST measurement data, demonstrating the utility of the proposed channel model.

Title: Future Railway Mobile Communications.


Abstract: High-speed railway (HSR) has brought much convenience for peoples’ travelling. To ensure safe and reliable operation of HSR, the train operation control system acts as a nerve center. To make such nerve center work well with less time delay, maintaining a reliable bidirectional communication link between the train and the ground, dedicated mobile communication systems such as GSM for railway (GSM-R) and LTE for railway (LTE-R) play key roles. Moreover, rapid growth of future railway services and applications such as real-time high-definition (HD) video surveillance has aroused 1 Gbps data transmission rate with 100 MHz bandwidth at least. Thus, higher frequency band such as mm-wave technique, the fifth generation (5G) technique and corresponding mobile communication network should be designed accordingly to provide high capacity and high data transmission rate for newly developed railway services and applications. In this presentation, the key techniques and challenges for GSM-R, LTE-R and the fifth generation technique such as massive MIMO implemented in HSR will be discussed.
