Coding for cooperation and relaying

Cooperative communications refers to network communication where nodes cooperate, rather than compete, to transmit data for themselves and others. The main goal of this talk is to review basic strategies for cooperative communications with particular emphasis on a method called “compress-and-forward”. This method has recently been used successfully to treat a variety of theoretical problems concerning relaying, e.g., determining antenna-clustering capacities, the diversity-multiplexing tradeoff, scaling laws of networks, oblivious communication rates, and suggesting problems for which cut-set bounds can be improved. Some of these results are reviewed in detail.
