matlab多径信道传播接收分析，通过码元产生，频谱观察，以及多径接收后的频谱观察，最后利用一个音频作为实际仿真，代码还有很多不足之处，希望能和大家一起交流学习。-matlab multipath channel propagation analysis received by symbol generator, spectrum was observed, and the spectrum observed multipath reception after the last use of audio as an actual simulation code, there are many shortcomings, and we hope to learn together with the exchange.
