一个小的lindo，做数学建模的同志们应该知道吧，不知道你们用得上不。以后有好东西再给大家送来(A small lindo, make mathematical modeling comrades should know, I do not know you is not useful. After the U.S. has brought good things to give)

qpsk modulation 这是从网上下载的。已经经过验证。(qpsk modulation which include the generation of random number, and eye diagram, power spectrual density)

主成分分析 还不错的程序 有需要的可以试试(pca for zhe value)

To make parameters easier to change and easier to determine their values, a GUI is supplied with this model. Radar and weather parameters may be changed from this GU

FFT频率提取的MATLAB实现，有具体的图形(FFT frequency extracted MATLAB realize, there are specific graphics)

fir滤波器，7、8、13、14，对信号进行alpha、betagamma滤波，调用方法 Hd = fir_alpha 滤波后信号 = filter(Hd,原信号) 得到的信号是时域信号，plot直接显示(Fir filter, 7, 8, 13, 14, alpha filter for signal method is called Hd = fir_alpha After filtering signal = filter (Hd, the original signal) Signal is time domain signals, the plot showed directly)
