说明：  通信原理的作业，利用matlab产生两路模拟语音信号，经过temp编码、时分复用、temp1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 temp, time division multiplexing, temp1 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.)
