In the previous chapters we have encountered a number of ways to process digital on

目前比较前沿的数值渐近法（Asymptotic Numerical Method）求解弹簧平衡路径算例，直接运行可得计算结果图象。(an example of Asymptotic Numerical Method solving two-dimension spring problem)

用matlab编写的三维魔方模拟显示，直接运行first.m即可(Three-dimensional cube simulation using matlab display, can be run directly first.m)

说明：  MATLAB 7编程 数字信号处理源代码(MATLAB )

可以将matlab中的mat文件转换成txt文件，方便其他的应用程序调用。(Mat files can be converted into a txt file and facilitate the application calls.)

用matlab 做的图像畸变校正源程序.主程序主要是做了一个图像处理的界面，并且实现图像的几何畸变校正，颜色畸变校正和图像模糊处理。外加几个子程序(Using matlab to do image distortion correction source main program is an image processing interface and image geometric distortion correction, color distortion correction and image blur processing. Plus several subroutines)

OFDM系统通过在时域符号前插入大于信道冲击响应长度的循环前缀（CP）可以避免符号间干扰(ISI)和载波间干扰(ICI)。但是，过长CP会使得数据传输效率降低。可以采用最小均方误差（MMSE）信道缩短均衡技术来压缩信道冲击响应长度。(OFDM systems avoid inter-symbol interference (ISI) and inter-carrier interference (ICI) by inserting a cyclic prefix (CP) larger than the channel impulse response length before the time-domain symbol. However, long CP will reduce the efficiency of data transmission. A minimum mean square error (MMSE) channel shortening equalization technique may be employed to compress the channel impulse response length.)

polar码编译码，采用SC译码，仿真可以成功(polar coding performed using SC decoding)

matlab图像处理源代码， 请放心下载(matlab image processing source code, please rest assured Download)

其中包含了两个用matlab编写的Zernike程序。(Which contains two Zernike prepared using matlab program.)
