将带发送数据序列映射为格雷码，相邻的码元只有一个符号不同。(mapping the deta serial into GeLei code,whose closed code only one symbol is different)

matlab 数字图像压缩 DCT实现，matlab本身有demo 但这里加固一下(digital image processing using matlab， enjoy yourself)

里面含有盲识别BCH码的长度的代码，用于matlAB子程序调试，很好用。(BCH code which contains the length of the blind identification code for matlAB subroutine debugging, very good use.)

清华大学信号处理原理课程第一次实验，内容为产生固定波形以及声波的叠加(Signal processing theory, Tsinghua course first experiment, the content and the acoustic waveform to generate a fixed superposition)

通过 MIMOsimSpectralHelp() 输入不同参数，可以模拟和比较在不同结构和环境下MIMO系统的性能；有助于我们理解MIMO。(Enter through MIMOsimSpectralHelp () with different parameters, you can simulate and compare the performance of different structures and environments in MIMO systems help us understand MIMO.)

几种去除基线漂移的方法,大家可以进行对比研究,个人认为还不错(Several methods to remove baseline drift, we can carry out comparative study, individuals consider good)

说明：  坐标转换：已知n个点在a,b两坐标系中的坐标值，采用优化方法求转换关系（标准的7参数转换关系，x,y,z的移动，x,y,z的旋转，以及缩放系数）ps:附带空间旋转公式。input: points in A and B。 output：transfer relationship （u,v,w: shit of x,y,z。 a,b,g: rotate of x,y,z 。k：zoom）(Coordinate Transfer:A,B are tow coordinates. This program using optimal method to find the transfer relationship of A and B. input: points in A and B。 output：transfer relationship （u,v,w: shit of x,y,z。 a,b,g: rotate of x,y,z 。k：zoom） )
