数字信号处理重要函数如分裂基fft/卷积/频率响应/滤波器的matlab实现（来自清华大学胡广书教授）(Important DSP functions such as fff/conv/frequency/filters, by matlab)

程序实现了直接序列扩频通信系统，简单易懂。(Program realization of the direct sequence spread spectrum communication system, straightforward.)

这是一段GPS信号产生的程序，里面包括对不同卫星星号产生的扩频码，同时以及产生对应的GPS信号。(This GPS signal is generated by a program section, which includes different satellites asterisk generated spreading codes, and simultaneously generates a corresponding GPS signal.)

函数Jf用来求所付代价的增加值，只要在matlab中输入Jf=Jf(a)得到的结果就是J了，其中a的值为对应的 值； 函数Rf用来求所收益增加值，只要在matlab中输入Rf=Rf(a)得到的结果就是R了，其中a的值为对应的 值； 如果要修改表格的值的话，就对应的修改函数Jf和Rf中的数组y的值就好了，M的值和N的值以及r的值都可以修改的。 (Used to demand the consideration paid for the increase in value of the function Jf, in matlab enter Jf = Jf (a) the results obtained is J, the value corresponding to the value of a function Rf used to ask or gains added value, as long as Rf = Rf (a) input in matlab result is R, where a value of corresponding value If you want to modify the value of the form, it corresponds to modify the function Jf and Rf array y values ​ ​ like , the values ​ ​ of M and N values, and the value of r can be modified.)

说明：  用matlab做的博士毕业论文讲解,里面包括算法值得参考(Using matlab to do a PhD thesis on, which include the algorithm it is also useful)

蒙特卡罗仿真程序，挺好用的，在此分享给各位朋友试用。(Monte Carlo simulation program, very good use, share with friends in this trial.)
