Title: Multi-Dimensional Correlation Exploited Cooperative Wireless Communications: Theoretical Analysis and Performance Evaluation
Abstract: In this talk, we investigate cooperative wireless communications from the perspective of network information theory. The primary goal is to create theoretical bases and establish practical code frameworks for cooperative wireless communications that exploit multi-dimensional correlations, and finally achieve new paradigm shift in wireless communication system design. Particularly, we focus on two representative problems: (1) Markov source transmission over one-way single relay system, (2) correlated source transmission over multiple access relay channel. For both problems, the achievable rate region is analyzed based on Slepian-Wolf and source coding with side information theorems, respectively. The performance limits of the two problems are then derived based on the achievable rate region analysis. We also proposed practical distributed joint source-channel coding and joint source-channel-network coding techniques for the two problems to exploit the source correlation, respectively. The effectiveness of the proposed coding techniques and the accuracy of the theoretical analysis are verified through a series of simulations.
