预失真补偿后的图形,采用快速傅里叶变换（Fast Fourier Transform, FFT） 计算得信号的频率数据，再利用得到的频率数据计算功放预失真补偿前后功率谱密度 样值(Predistortion compensation of graphics, using the Fast Fourier Transform, Fast Fourier Transform and FFT) Calculate signal frequency data, then get the frequency of the power spectral density before and after data computing power amplifier predistortion compensation Sample values)

实现信号处理的一个例子，对于学习资源的同学很有用(realize voice control,it is good for you!!)

利用matlab绘制等距指数坐标部分程序，参数自己修改，仅供参考。(Index of use of matlab to draw isometric coordinate part of the program, modify the parameters themselves, are for reference only.)

基于支持向量机算法的分类程序，matlab实现。(Algorithm based on support vector machine classification procedures, matlab implementation.)
