time reversal technique for uwb communication

被动时间反转镜和直接扩频相结合，有效克服多途环境。(The combination of passive time reversal mirror and direct spread spectrum can overcome multipath environment effectively.)

本代码为单阵元时反实验，研究了simo系统，并仿真不同SNR下的误码率。(the code is foucs on time reversal mirror, based on simo. simulated the ber under different snr.)
