基于联合迭代检测译码的多中继RA编码协作系统
Multi-relay RA coded cooperation system based on joint iterative detection decoding
摘要
Abstract
In order to improve the system performance,a multi-relay coded cooperation communication system based on re-peat accumulation(RA)code is proposed. The RA code is used at the source node and relay node of the system. The multi-layer Tanner graph corresponding to the reception codon of the destination node is deduced. A new coding method based on the multi-layer Tanner graph and MAP algorithm is used to realize the joint iterative detection decoding,and signal detection of the desti-nation point. The theoretical analysis and numerical simulation results show that the new method can realize the potential diver-sity and coding gain owned by multi-relay coded cooperation,with the increase of the internal and external iterations,the perfor-mance of the bit error rate(BER)is superior to that of the coded non-cooperation system.关键词
