用MATLAB编程 主要讲解小波变换的一些知识包括源代码，适用于研究小波变换的人(Mainly on the use of MATLAB programming knowledge, including some of the wavelet transform source code, for the people of wavelet transform)

this program it is first step in construct magic square in genetic algorithm it has some function and i will upload again now i finish

通过matlab仿真了Saleh-Valenzuela 信道模型，仿真图有四个子图，（a）和（b）分别示出的分布的群集抵达时间和射线到达时间，（c）表示S-V信道的脉冲响应，（d）图显示了信道功率分配(Saleh-Valenzuela channel model by matlab simulation, simulation diagram there are four sub-chart, (a) and (b) respectively illustrated the distribution of cluster arrived in time and the ray reaches the time, (c), said the SV letter tract of the impulse response (d ) The figure below shows the distribution of channel power)

说明：  信号处理,进行信号检测与处理，通过设定threshold来进行信号检测的可信度调整(Credibility adjustment signal processing, signal detection and processing, by setting threshold for signal detection)

image and signal processing are used mostly right now. these programs is related to image processing. Image negative is used for the getting the negative image of the original image. and contrast stretching is for the give the middle value. Fast Fourier Transform program is used for the getting FFT of the signal.

SPS 运动平台可达工作空间程序,可以根据其计算并联机器人达到的工作空间(SPS 运动平台可达工作空间程序)

Lossy Run Length coding and decoding

水印嵌入算法，可实现彩色水印的嵌入，很有用的(Watermark embedding algorithm, the watermark can be embedded in color, very useful)

实现信道的交织解码和解交织解码，用于OFDM通讯系统中(Achieving channel interleaving decoding decoding deinterleave)

说明：  设基带码元传输间隔为0.1秒，FSK调制参数分别设置频率间隔为5Hz和20Hz，相位分别设置为不连续的和连续的两种。试对比观察4元FSK调制输出等效低通信号的功率频谱。(Let the baseband symbol transmission interval is 0.1 seconds, FSK modulation parameters are set the frequency interval of 5Hz and 20Hz, respectively, set to the discontinuous phase and continuous two. Observation of test 4 yuan FSK modulation output equivalent low pass signal of the power spectrum.)
