小波函数，网上找来共同学习，希望大家能用得着(Wavelet function, the Internet got to learn together, and hope that we can need it)

说明：  OFDM,里面的源程序经过调试可以使用，大家参考参考(OFDM, which can debug the source code through the use of your information)

ASK FSK PSK DPSK 图形描述 (ASK FSK PSK DPSK graphic description)

产生一个长为1000的二进制随机序列，“0”的概率为0.8，”1”的概率为0.2； 对上述数据进行归零AMI编码，脉冲宽度为符号宽度的50 ，波形采样率为符号率的8倍，画出前20个符号对应的波形（同时给出前20位信源序列） 改用HDB3码，画出前20个符号对应的波形 改用密勒码，画出前20个符号对应的波形 分别对上述1000个符号的波形进行功率谱估计，画出功率谱 改变信源“0”的概率，观察AMI码的功率谱变化情况(A length of 1000 random binary sequence, and " 0" with a probability of 0.8, " 1" with a probability of 0.2 the AMI code above zero, the pulse width of the symbol width of 50 , the waveform sampling rate Symbol rate 8 times, draw the top 20 of the waveform corresponding to the symbol (the first 20 and gives the source sequence) switch HDB3 code, the first 20 to draw a waveform corresponding to the symbol to switch Miller code, the first 20 symbols correspond to draw The waveforms of the symbol of the waveform 1000 power spectrum estimation, shown to change the source power spectrum " 0" , the probability of observation of the power spectrum of AMI code changes)

多模态数据的特征提取方法：时间序列数据及DTW高斯核,图像数据及直方交核 和字符串数据及字符串核(Feature extraction method of multi modal data, time series data and DTW Gauss, the image data and the histogram intersection kernel and string data and String Kernel)

压缩感知算法工具箱，可以将压缩感知用于想用的任何算法。(The Compression Sensing Algorithm Toolbox allows you to use compression awareness for any algorithm you want to use.)

说明：  FAST ICA算法，用于多个信号盲分离，可以参考一下，挺不错的(Fast ICA algorithm, used for blind separation of multiple signals, can refer to, very good)

说明：  本章的内容更深入MATLAB可视化功能的内核。编写本章的目的有两个：一，使读者更深入地理解高层绘图指令，从而可绘制出更精细更生动更个性的图形；二，使读者能利用低层图形指令和图形对象属性开发专用绘图函数(This chapter more in-depth visualization of the core MATLAB. The purpose of the preparation of this chapter, there are two: First, make readers more in-depth understanding of high-level graphics commands, which can draw out the finer more vivid and personalized graphics 2, so that readers can use low-level graphics commands and graphics object properties developed special drawing functions)
