对matlab中的常用函数进行补充，对信号处理的实现有帮助，只要将其加入默认路径就能轻松使用。(the commonly used matlab functions added that implementation of signal processing has to help, as long as its default path will be able to add easy to use.)

This is a solution manual of Probability of random signal.

说明：  能够清晰的分析线性调频信号的频谱特性，能够很好的帮助理解lfm信号(Can clear analysis of linear FM signal spectrum characteristics, can be very helpful in understanding LFM signal)

基于PEG算法的准循环LDPC码构造方法研究(PEG algorithm based on quasi-cyclic LDPC code construction methods)

基于MATLAB实现了极坐标下的傅里叶变换，对一个给定 n×n 的二维信号，其计算复杂度等价于笛卡尔坐标下的2D-FFT，可广泛应用于图像处理和分析。(A fast high accuracy Polar FFT algorithm is given in the software package written in MATLAB. For a given 2D signal of size n×n, the algorihtm s complexity is just like in a Cartesian 2D-FFT, which can be used widely in image processing and analysis.)

阵列信号的经典算法capon波束形成器，也就是capon算法，也可以用来估计波达方向（DOA）(Array signal of the classic capon beamforming algorithm is also is capon algorithm, also can be used to estimate the wave of direction (DOA) )

画出地貌地形图，熟悉各个matlab语句的掌握与运用，掌握运用插值函数的调用格式，对各种调用函数的格式语句要能够熟练的应用(Draw terrain map, master and use the MATLAB statement, master the use of interpolation function call forms, application format statement of a function call to be able to )

模糊逻辑的matlab工具箱，和matlab自带的工具箱不同。里面包含了更多的应用函数。(Fuzzy logic toolbox of matlab and matlab different built-in toolbox. Which contains the application of additional functions.)

语音分帧程序，对一个语音信号进行分帧，并研究分帧后的短时能量和过零率特性(Voice framing procedures, a voice signal framing, and to study the sub-frame after the short-term energy and zero crossing rate characteristics)
