Executive Summary

Wireless relay networks have attracted much attention recently, since they can provide better coverage and/or higher network throughput, and hence improve the overall system performance. When multiple relays are available, they can be further exploited to obtain macroscopic diversity/multiplexing gain. Different relay protocols have been studied widely to improve the spectral efficiency and system performance. These relay protocols are designed mainly for the Amplify-Forward (AF) and the Decode-Forward (DF) relay systems. The relays are often assumed to be half-duplex, since full-duplex relays are often difficult and expensive to implement.
