说明：  基于matlab的编程，信道仿真的，很好很强大(Matlab-based programming, channel simulation, very good very strong)

无网格法权函数求解子程序，需要和以上载的第一个程序和用！(without grid power function for subroutines, and the need to contain the above procedures and the use of one!)

Cosecant Beam Generation Program for computing Phase distribution function and Radiation pattern.

说明：  the best way to learn ac electronics

非平稳噪声下，通过预处理，可以很好的消除噪声的影响，且能对信号解相干(Non stationary noise, through pretreatment, can be very good to eliminate the influence of noise, and to signal decorrelation )

北邮宋同学的matlab的天线方向图计算软件，里面集成了多个天线的计算，界面操作简单，并且里面给出了软件的MATLAB程序，仔细研读，收获匪浅(Song BUPT students matlab antenna pattern calculation software, which integrates the calculation of multiple antennas, simple interface operation, and which gives the software MATLAB program, carefully read, harvest a great deal)

基于最小均方误差估计(mmse)的语音增强算法的研究的相关资料，期刊，论文(Based on the minimum mean square error estimation (mmse) speech enhancement algorithm relevant information, journals, papers)

用matlab实现低通滤波器。采用的是FIR低通滤波器实现。(Low pass filter with matlab. Using the FIR low-pass filter.)

他能把前后景分开，把前景去除掉，形成稳定的背景图(He can separate foreground and background, the foreground removed to form a stable background)
