协作通信，一个最基本的decode and forward程序。用卷积码和viterbe译码。可以作为复杂程序的原型-Collaborative communications, a basic decode and forward procedures. With convolutional codes and decoding viterbe. Complicated procedures can be used as a prototype

这个程序用蒙特卡洛法计算了单小区用户利用D2D通信解码转发中继选择情况下的误码率(This program calculates the bit error rate of single cell users using D2D communication decode and forward relay selection)
