用于测定传递函数的matlab程序,可以直接调用用于测定传递函数(the basic funtion to get a system transfunction，and it can be called easily)

一个turbo码的仿真程序，输入Eb/N0值，随着传输帧的增加，误码率增加，得到400帧的误码率。(a turbo code simulation program, the value of imported Eb, with the transmission of the frame, BER increasing, and the 400 bit error rate.)

Multipath vs estimation error is simple cooperative communication using matlab

一个做中频处理的matlab仿真源程序，通信系统专用(IF processing matlab to do a simulation of the source process)

This algorithm is reserved to the implementation of the Bahl, Cocke, Jelinek and Raviv (BCJR) algorithm. This function take as input the channel output (corrupted data) and the a priori prob (we will set it to 1/2) and returns as output the APP Log Liklihood Ratio (LLR) for every data input. It is usually called a Soft Input Soft Output (SISO) decoder. It can be applied to any code having a finite state machine, in our case we will use it for rate-1/n convolutional codes.

说明：  EM最大期望算法：算法是在概率模型中寻找参数最大似然估计或者最大后验估计的算法，其中概率模型依赖于无法观测的隐藏变量。最大期望经常用在机器学习和计算机视觉的数据聚类领域。(EM algorithm)
