利用一数学仿真工具构建一16-QAM的通信系统 工具：推荐使用Matlab,可使用信号处理工具箱但不能利用通信工具箱(The use of a mathematical simulation tools to build a 16-QAM communication system tools: Recommended use of Matlab, Signal Processing Toolbox can be used but not the use of communication toolbox)

该模块实现信号的相位调制和解调，进而的到原始的输入信号。(This module implements the phase modulation and demodulation signal, and then to the original input signal.)

是matlab写的求解哈夫曼编码的程序。(is written in Matlab for Huffman coding procedures.)

说明：  有关LBP的的五个小程序，希望对研究该领域的人有所帮助(Related LBP of the five small programs, I hope to research in the field who help)

空间谱估计（郑志东） 的程序 很多章 全( Spatial spectrum estimation (Zheng Zhidong) program many chapters all)

使用Harris角点检测方法进行图像特征点提取,NCC描述的方法进行粗匹配,再使用RANSAC算法进行精匹配。(Using Harris corner detection method for image feature point extraction, NCC description of the method of rough matching, and then use the RANSAC algorithm for fine matching. )

自相关虽然能够判断清/浊音，并估计浊音的基音周期，但是其运算量很大，用乘法运算所需时间较长。为了避免乘法，采用短时平均幅度差函数（AMDF），验证AMDF与自相关有类似的作用，即平均幅度差函数能够代替自相关函数进行语音分析。(Although autocorrelation can differ from the Voiced/Unvoiced and voiced the pitch period estimate, but the operation is large enough, with the multiplication time was needed. In order to avoid the multiplication using the short time average magnitude difference function (AMDF), verify the AMDF and autocorrelation have a similar effect, that the average magnitude difference function can replace the voice of the autocorrelation function.)
