Abstract:In this paper,we study the transmit diversity receiving method and its performance under the condition of multipleinput multiple output (MIMO)system in Rice fading channel. A new idea of tradeoff between transmission rate and outage probabilityof multi antenna relay network is proposed. By applying the decode and forward protocol,Under the condition of high and lowSNR,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 inmultiplexing gain.
