应用于变量选择的PCA 和 PLS 程序！利用它可以选出独立的变量数!在化学中很有用！(for variable selection procedures PCA and PLS! It makes it possible to elect independent variables! In Chemistry useful!)

说明：  该仿真模型是用来提取单机无穷大系统发生故障短路各线路三相电压的最大值(The simulation model is used to extract single machine infinite bus system short-circuit failure of the maximum three-phase voltage of each line)

This is a GUI based system. The GUI is invoked from the command line by typing "ui_start". The GUI is self explanatory. Tool tips are given in blue color. The cursor needs to be positioned on these for detailed explanation. The main file is "runsim.m".It is recommended that 10000 runs (packets) be used for plotting frame error rates and 5000 runs for BER/SER. Obviously, you would require a fast machine!!! At least a P4 machine. We have used trace criterion for 4PSK states 4,8 and 16 as an example for 2x2 cases. The reader can use rank and determinant criteria, by commenting the trace criterion lines and copying the rank and determinant lines from the respective 2x1 cases. The SNR range can be varied by correcting the range at line 36 of file "runsim.m". This software has been tested with MATLAB version 6.0 and above with signal processing and communications toolbox options. (This is a GUI based system.

此matab函数文件可以用来计算模型的李雅普诺夫指数，用于稳定性分析。(this Lyapunov.m file can be used to compute the lyapunov exponential)

Inspired with scramble game in android, a algorithm for searching dictionary words based on the traversing of 4x4 word matrix. taking long time to run but a novice idea.

基于多模型粒子滤波的机动微弱目标检测前跟踪的matlab仿真实现(multiple model particle filter based track-before-detect for moneuvering weak target)

This code proved to an efficient code for image compression using wavelet transform

说明：  这是一个关于dQPSK的Matlab程序 这是一个关于dQPSK的Matlab程序 (This is a dQPSK the Matlab program This is a dQPSK the Matlab program)
