说明：  通信原理的作业，利用matlab产生两路模拟语音信号，经过SMNFtd编码、时分复用、kBZpdqL调制经过同一个信道单向传输到对应的接收端。仿真了端到端通信的链路质量和丢包率情况，测试完整可用。.
(Communication Theory of operations, the use matlab to generate two analog voice signals encoded through SMNFtd , time division multiplexing, kBZpdqL modulation over the same one-way transmission channel corresponding to the receiving end. Simulation of the link quality and packet loss rate case end communications, testing complete available. )
