code

对粒子群算法改进的算法，其各性能有很好的改进(Improved particle swarm optimization algorithm, its performance is very good improvement)

本程序画混沌的Chen系统,程序简单切运算速度快.(This procedure painting chaotic Chen system, the program simply cut operation is fast.)

先用NEXT对进行出来了，消除噪声的影响，然后再用ARMA进行处理。(NEXT carried out on first use, and eliminate the noise, and then use the ARMA processing.)

通信PSK调制fsk调制，按定义编写，及相应的误码率计算，里面用到GUI界面，大家可以从相应的代码中截取自己需要的部分(Communication PSK modulation fsk modulation, by definition, write, and the corresponding bit error rate calculation, which uses GUI interface, you can intercept the part they need the corresponding code)

PARSING DATA IN MATLAB ALGORITHM

说明：  基于MATLAB的有源滤波器的实现，很简单，能看懂。(The realization of active filter based on MATLAB is simple and understandable.)

本程序为应用小波变换进行信号压缩。由于本程序涉及到了小波变换的函数，因此可能涉及到一些时频分析工具箱的函数。程序中应用db3小波进行3层分解，选用全局阈值进行阈值处理，即对各高频系数使用同一个阈值，进行阈值处理。(This procedure for the application of wavelet transform for signal compression. Since this procedure involves the wavelet transform of the function, it may involve a number of time-frequency analysis function of the toolbox. Procedures for the application of layer 3 to db3 wavelet decomposition, selection of the overall threshold threshold treatment, that is, on the high-frequency coefficients using the same threshold, the threshold for treatment.)

a good algorithm for classification performance improvement (use PCA and LDA respectively and then implement the resulted data set into your classifier)
