四发天线DSTTD编码系统性能分析

Performance Analysis of Four Antenna DSTTD Coding System

在无线通信系统中,适合多输入多输出(MIMO)天线技术的空时编码技术能够明显地提高系统的容量,改善无线通信系统的性能。文章在空时分组码(STBC)基础上,对四发射天线DSTTD编码系统进行了编译码介绍,并进行了误码性能的仿真,最后得出结论。

In the wireless communication system, suitable for multiple input multiple output （MIMO） technology of empty when coding technique can signiifcantly improve the system capacity and improve the performance of wireless communication system. The in space-time block codes （STBC） based on, for four transmit antennas DSTTD coding system was compiled codes are introduced, and Simulation of the bit error rate （BER） performance, ifnally draws the conclusion.
