一套完整的雷达仿真程序，雷达的各个部分的完整仿真，(A complete set of radar simulation program, the radar part of the integrity of the various simulations,)

A good tool box to learn chaotic phenomenon!

详细的介绍了有关HMM模型的基本思想，是一本很好的资料！(Detailed introduction of the HMM model of the basic idea is a very good information!)

按照人名 电话号吗的格式建立电话本，再执行时把文件名作为参数。带有语音功能。(accordance with the names of persons telephone number? Format established telephone, and implementation of the document as a parameter. With voice.)

此为基于二代提升小波的阈值压缩算法源码，其中可以设置小波变换的分解层数，使用的小波名称，及各层阈值设置计算公式中的参数。并将低频系数转化为十六进制，方便在其上进一步压缩，如采用Huffman压缩等，程序思路清楚，附有完整的注释，可以使用多种小波，并且很好得体现了二代小波的思想，对于初学小波者帮助很大。(based on the second generation of this upgrade wavelet compression algorithm threshold source, which can set wavelet transform decomposition level, the use of wavelet name, threshold levels and set the formula for calculating the parameters. And low-frequency coefficients into hexadecimal facilitate its further compression, such as the Huffman compression. procedures ideas clearly, with the integrity of the Notes, you can use a variety of wavelet, and reflected very well in the second generation wavelet thinking, For beginners who wavelet of great help.)

采用自相关函数法求基音周期，将采样得到的声音信号按每20ms一帧分为若干帧，并对每帧的序列求自相关函数，取自相关函数第一个最大值点算出基音周期，并以帧为横坐标，基音周期为纵坐标画图，并去除野点，最后取图中浊音部分即面积较大部分的值作为基音周期。(Using the autocorrelation function method pitch period, the sound signal is sampled every 20ms frame is divided into a plurality of frames, and each frame sequence uates the autocorrelation function, taken the first maximum point of correlation function calculated the pitch period, and frame as the horizontal, the vertical axis pitch drawing and remove outliers, and finally take the value of the area that is part of a larger portion of the figure as voiced pitch.)

说明：  产生一定频率的正弦信号，并利用matlab函数加瑞利噪声和高斯噪声，模拟传输信道的衰落，最后画图对比加噪前后的信号。(Adding Rayleigh noise and Gaussian noise to a given signal)
