摘　　要：本文研究了基于莱斯衰落信道的多输入多输出(MIMO)系统的发射分集接收方法及其性能。提出了多天线中继网络传输速率与中断概率之间折衷关系的新见解。通过应用解码转发协议,研究高低SNR条件下,将分集复用折衷(DMT)的概念作为说明MIMO系统性能的工具。数值结果表明,研究方案所使用的多路分集复用增益较直接链路传输有显著性能优势。In this paper,we study the transmit diversity receiving method and its performance under the condition of multiple input multiple output(MIMO)system in Rice fading channel.A new idea of tradeoff between transmission rate and outage probability of multi antenna relay network is proposed.By applying the decode and forward protocol,Under the condition of high and low SNR,the concept of diversity multiplexing compromise(DMT)is used as a tool to illustrate the performance of MIMO system.The numerical results show that the proposed scheme can provide significant performance advantages over direct link transmission in multiplexing gain.
