Analysis and Simulation of Performance of Space-time Block Coding

空时编码作为无线通信中一种新的编码和信号处理技术,它使用多个发射和接收天线进行信息的发射与接收,可以大大改善无线通信系统的信息容量和信息率。本文着重分析了空时编码中的空时分组码,并借助MATLAB仿真平台对其误码性能进行仿真。结果表明,随着发射天线和接收天线数目的增加,其误码性能明显改善,具有较高的实用价值。

Space-time Code is a new code and signal processing technology of wireless communications, it uses more than one transmitting and receiving antennas, and can greatly improve the capacity and rate of wireless communication system. This article mainly analyses the performance of space-time block code, and simulates the bit error rate （BER） of STBC system on the platform of MATLAB. The simulation results show that greatly improve the system performance on STBC system and this system is available to the practial value.
