语音识别系统，在静音环境比较准确，但是假若有噪音或者其他情况会有问题，附预处理部分(Speech recognition system, in the quiet environment is accurate, but if there are noise problems or other conditions will be attached to some pretreatment)

this code is a matlab code for smithchart that I onlt modify this but this is very useful for communication enginnering

Monte Carlo方法的实质是通过大量随机试验，利用概率论解决问题的一种数值方法，基本思想是基于概率和体积间的相似性。它和Simulation有细微区别。单独的Simulation只是模拟一些随机的运动，其结果是不确定的；Monte Carlo在计算的中间过程中出现的数是随机的，但是它要解决的问题的结果却是确定的。(The essence of the Monte Carlo method is a numerical method to solve the problem through a large number of randomized trials, the use of probability theory, the basic idea is based on the similarity between the probability and volume. There are subtle differences between it and Simulation. Separate the Simulation simulation of random movement, the result is uncertain number of the Monte Carlo calculations in the middle of the process is random, but it is to solve the problem the result is determined.)

详细介绍了MATLAB的基础，并结合实例讲解了其应用(Details of the basis of MATLAB and explain with examples of its application)

说明：  RS码的C实现，通过mex接口，在MATLAB中创建的LTE下行链路中测试，可跑出误码率曲线。(RS code is implemented in C, by mex interface, LTE downlink created in MATLAB test can be run out of BER curves.)
