说明：  OFDM的QPSK仿真程序，里面只有一个txt文件，所有程序都在上面了。(OFDM QPSK simulation program, only a txt file, all proceedings in the above.)

光通信中3*3耦合器相位解调的仿真，包括对称解调与非对称解调两种。(Optical Communication 3* 3 coupler phase demodulation of the simulation, including demodulation and demodulation of two symmetric asymmetric.)

对qpsk一个整体的仿真，从源信号的生成，调制，加载波，解调等，步骤清晰，与通用教材原理图逐步仿真而来(Qpsk simulation of a whole, the signal generated from a source, modulation, plus carrier demodulation step clarity, and general simulation of materials gradually from the schematic)

李国勇 编著 北京，电子工业出版社 自动控制技术应用丛书 2005 这本书上的例题的源代码(Edited by Li Yong Beijing, Publishing House of Electronics Industry Series 2005 automatic control technology applications on the book' s example source code)

说明：  这个一个用matlab写的关于二值图像游程编码的实例(binary image coding)

数字图像预测压缩编码程序，基于matlab软件(The code of prediction for image compression.)

随机信号谱分析 基于matlab 随机信号的频域谱分析 自谱 互谱 窗函数等 十分实用(Spectral analysis of random signals Matlab random signals based on spectral analysis of frequency-domain cross-spectral window function from the spectrum of other very useful)

说明：  线性判别分析（LDA）：将高维的样本投影到最佳鉴别矢量空间，来达到抽取分类信息和压缩特种空间维数的效果，投影后保证样本在新的子空间有最大的类间距离和最小的类内距离。(Linear discriminant analysis (LDA): projects high-dimensional samples into the best discriminant vector space to extract classification information and compress the dimension of special space. After projection, it ensures that the samples have the maximum inter class distance and the minimum intra class distance in the new subspace.)
