Coded Cooperation with Permutation and Block Encoding for Wireless Networks

A novel coded cooperation scheme based on the intersection of interleaved block codes is proposed for multi-source multi-relay networks. Specifically, the multiple source data are jointly encoded and forwarded to the destination by multiple cooperative relays while the sources and relays have low complexity. In this way, a distributed coding scheme with permutation and block encoding is constructed to achieve diversity and coding gains simultaneously. The scheme can achieve significant performance gain over direct transmission and fit for cooperative networks with different number of sources or relays.
