Abstract

An efficient distributed Alamouti Space-time coded relay cooperation scheme is proposed over a Rayleigh fading channel, where structured irregular systematic low-densityparity-check (LDPC) codes are employed. In the known channel state information (CSI) scenario, a concatenation of combiner and joint iterative decoder is effectively carried out in the destination. The theoretical analysis and numerical simulations show that the proposed LDPC-coded cooperation scheme can well combine diversity and channel coding gain, and clearly outperforms the conventional cooperation under the same conditions.
