计算两幅图像的峰值信噪比。图像是表示地个像素点所用的二进制位数，即位深。计算PSNR(Calculate PSNR of two images. Image pixel is expressed in a number of bits used, ascended the throne deep. Calculation of PSNR)

用于复杂背景下的背景提取，比如高速公路等等，效果非常好(background extract background extract)

本程序设计的是咬尾编码的turbo码，用matlab编写。咬尾turbo码也即不需要拖尾比特，使得前后两个状态相同，译码采用修正的MAP译码算法。此文件为咬尾编码矩阵生成的测试文件包(This program is designed to encode the turbo tail biting code, written with matlab. Tail biting turbo code that is not trailing bits to make the same before and after the two states, the MAP decoding using modified decoding algorithm. This file is biting the end of the generated test code matrix package)

基于Matlab编程环境下的程序，SIFT目前比较热门的特征提取程序。(Matlab programming environment based on the procedure, SIFT now more popular feature extraction process.)

利用matlab实现简易的MIMO系统仿真，其中包括AWGN信道和瑞利信道的2发2收有无信道编码的比较，以及1发2收。(Using matlab to achieve a simple MIMO system simulation, including the relatively AWGN channel and Rayleigh channel of the two 2 admission with or without channel coding, as well as a 2 admission.)

2ask的调制解调，包括相干解调和非相干解调，并有两者的性能分析(2ask modem, including coherent demodulation and non-coherent demodulation, and performance analysis of both)

自己编的识别手写数字的程序 大家随便看看吧(Own hand-written digit recognition process we just take a look at it)

产生以群结构运动的多个目标的模拟运动轨迹 参数可调(group tracking data)
