受Arikan提出的信道极化思想的启发,对信源-中继-信宿的MIMO中继通信的上行-极化和下行-极化系统提出一种极化-转发MIMO中继通信方案.采用极化-转发方式传输数据,MIMO信道通过极化编码对源节点数据进行编码,目的节点采用连续消除解码算法进行解码,中继节点仅需要简单的编码而不需要完成繁重的译码任务,比传统的解码、解码转发和放大转发等中继方案具有更高的传输可靠性,传输信息被嵌在递归特性的极化码中,具有较低的解码复杂度.仿真结果表明,提出的极化-转发MIMO中继方案具有较好的BER性能.
Inspired by Arikan’s idea of channel polarization, a Polarization-Forwarding (MIMO) relay communication scheme is proposed for uplink-polarization and downlink-polarization systems of MIMO-relay communication in source-relay- The data is transmitted by the forward-backward mode. The MIMO channel encodes the source node data by polarization coding, and the destination node decodes by using the continuous elimination decoding algorithm. The relay node only needs to perform simple coding without carrying out heavy decoding tasks, Decoding, forwarding and amplifying and forwarding relay scheme has higher transmission reliability, transmission information is embedded in the recursive polarization code with lower decoding complexity.The simulation results show that the proposed polarization - Forwarding MIMO relay scheme has good BER performance.
