segmation

An implementation of Lempel Ziv coding for small size files. You can see compression for files if the file is redundant.

基于双平行线阵的声矢量传感器的MUSIC算法 用于在高斯白噪声环境下估计信号的到2维达角度 (MUSIC algorithm based on dual parallel linear array of acoustic vector sensor it can be used to estimate the signal in Gaussian white noise environment to the two Vader angle)

层次分析法（Analytic Hierarchy Process，简称AHP）是将与决策总是有关的元素分解成目标、准则、方案等层次，在此基础之上进行定性和定量分析的决策方法。(AHP (Analytic Hierarchy Process, the AHP for short) is the elements related to the decision is always broken down into objectives, principles, scheme, such as level, on the basis of the decision-making methods of qualitative and quantitative analysis. )

说明：  通信中PSK MATLAB代码，希望对大家有帮助！(Communication PSK MATLAB code, we want to help!)

仿真程序：首先需要用一个随机发生器产生（0.1）内的均匀随机数，然后再将该序列映射到对应的幅度电平｛Am｝。然后将这个范围再分成4个相等的区间，这些子区间分别对应于4个信号比特的符号00，01，10，11。检测器观察到r=Am+n，并且计算r和4种可能传输的信号幅度之间的距离，它的输出Bm就是相应于最小距离的信号电平。Bm与真正的的传输信号幅度比较，差错计数器用来对检测器产生的差错计数。(Simulation program: first need to use a random generator (0.1) the uniform random number, then the sequence is mapped to the corresponding amplitude level {Am}. Then this range has been divided into four equal intervals, these sub-intervals corresponding to four signal bits of the symbol 00,01,10,11. Detector observed r = Am+ n, and calculate r and 4 possible transmission distance between the signal amplitude, its output corresponding to the minimum distance Bm is the signal level. Bm and the real rate of transmission of the signal comparison, error detection counter is used to generate the error count.)

The programs are realted to communication and Image Processing. The Simulatin of Additive White GAussian Noise using Modulation is shown.
