说明：  直扩信号BPSK的仿真，采用异或移位的算法实现PN码达到扩频的目的(BPSK DS signal simulation, using different algorithms, or shift the PN code to achieve the purpose of spreading)

中值滤波和它的改进 自己实现的 可能比较粗略 matlab2013运行通过(Median filter and it is possible to achieve improved their sketchy matlab2013 run through)

生成反射系数的，希望对大家有帮助,是我们实验室用做地震资料处理流程中合成地震反射系数用的，具体看程序就知道。(you can see chinese explane,)

此程序为在matlab仿真软件中进行仿真的程序，对无线信道进行了仿真，考虑了雨衰、荫影等影响。(my english is very very poor.)
