DPCM,由于语音信号的相邻抽样点之间有一定的幅度关联性，所以，可根据以前时刻的样值来预测现时刻的样值，只要传预测值和实际值之差，而不需要每个样值都传输。这种方法就是预测编码。-DPCM, as a result of voice signals between adjacent sampling rate of a certain relevance, we can kind of time based on previous values to predict the kind of val

全速率语音突发的的发送端总程序，其中包括预编码，卷积编码，交织，调制等步骤的matlab程序，内付详细说明文档-Matlab program, which pay full rate speech sudden sender program, including pre-coding, convolutional coding, interleaving, modulation step detailed documentation

利用matlab simulink产生两路模拟语音信号，经过pcm编码、时分复用、DPSK调制经过同一个信道单向传输到对应的接收端。常用的三个模块 simulink、通信模块、信号处理模块。包括课程设计报告。-Using matlab simulink produce two analog voice signals through the pcm encoding, time division multiplexing, DPSK modulation over the same one-wa
