摘　　要：无线通信要解决的基本问题是使资源利用更合理、网络覆盖范围更广、系统容量更大、带宽利用率更高。MIMO(Multiple Input Multiple Output)多输入多输出技术和协同分集技术可以有效解决上述问题,已经成为下一代无线通信系统的关键热点技术。文章将MIMO技术与协同分集技术结合在一起,构建了一个2×2多天线单中继协同分集系统,应用Matlab软件对系统的误码性能进行仿真分析。The basic problem for wireless communications is to make more rational use of resources,wider network coverage,the system greater capacity,and higher bandwidth utilization.MIMO（Multiple Input Multiple Output） technology and multi-input multi-output cooperative diversity technology can effectively solve these problems,and have become a key hot technology of the next generation of wireless communication systems.The paper constructs a multi-antenna single relay cooperative diversity system combing MIMO technology and collaborative diversity techniques,and applies Matlab software to simulation analysis of the system error codes.
