MATLAB下的瑞利多径信道仿真，经过验证，可以使用(MATLAB under the multipath Rayleigh channel simulation, after verification, you can use)

说明：  matlab在数字信号处理中的应用。随着数字信号处理的发展，matlab可以非常方便的进行数字运算和逻辑判断。(matlab in digital signal processing applications. With the development of digital signal processing, matlab can be very convenient for digital computation and logic to judge.)

matlab基础教程，帮助用户了解matlab各项功能(Matlab basic course, help users understand the matlab functions )

运用matlab编程语言，实现利用Householder变换和Givens变换求解矩阵的QR分解(Use matlab programming language, the realization and the Givens transformations using the Householder transformation matrix QR decomposition to solve)

本书基于MATLAB 5.2版，提供了使用MATLAB的实践性指导。MATLAB已成为适合多学科、多种工作平台的功能强大、界面友好、语言自然并且开放性强的大型优秀应用软件，同时也已成为国内外高等院校高等数学、数值分析、数字信号处理、自动控制理论以及工程应用等课程的基本教学工具。本书按逻辑编排，自始至终用实例描述；内容完整且每章相对独立；是一本简明的MATLAB参考书，既适用于初学者，也适用于高级MATLAB用户。对MATLAB与FORTRAN、C等语言结合的描述更是所有MATLAB书籍中少有的一大特色。 本书适合作为理工科高等院校研究生、本科生教学用书，也可作为广大科研工程技术人员的自学用书。

2PSK和 2DPSK信号的调制与解调性能比较分析(Comparative analysis of modulation and demodulation performance and 2DPSK signal 2PSK)

exercise 4.11 of the book "informatioin theory,inference,and learning algorithm"

针对信号分选的常见算法，包括sdif（序列差直方图）算法，可以解决类似于固定重频信号，抖动重频信号，滑变重频信号和参差重频信号的分选等(For several common signal sorting algorithms, including pri transform, sdif (sequence difference histogram) algorithm, cdif (cumulative difference histogram) algorithm, can solve similar fixed repetition frequency signals, jitter signal repetition, repetition becomes slippery sorting and mixed signal repetition frequency signals, etc.)

package_emd,非常重要的工具箱，用于EMD的数字信号分解(package_emd, a very important kit for digital signal decomposition EMD)

这个是LBP人脸算法，对学习者有很好的帮助，关于人脸表情识别，这里是基于ORL人脸库。(This is the human face LBP algorithm, the learners have good help, on facial expression recognition, here is based on the ORL database.)
