全部的一个重构算法--子空间追踪方法matlab例程

基于matlab7.0,德尔菲大学的源代码，遗传算法工具箱(targetalloc)

此代码是有关QAM的MATLAB的仿真，包括4QAM,16QAM,64QAM。还有其误码率的仿真(This code is related to the MATLAB simulation QAM, including 4QAM, 16QAM, 64QAM. Also its BER simulation)

利用MATLAB分别用FFT和HARR小波进行了信号功率谱的估计，程序简单实用。(FFT, respectively, with the use of MATLAB and a signal HARR wavelet power spectrum estimation, the procedure is simple and practical.)

hybrid particle swarm optimization

说明：  利用BP神经网络进行图像分割。主要适用于RGB信息丰富的图像。以RGB为BP网络的三个输入，与对应的灰度图对网络进行训练。(The use of BP neural network image segmentation. RGB is mainly applied to information-rich images. BP network to RGB for the three inputs, with grayscale corresponds to the network training.)

基于matlab的小波图像降噪，亲测调试成功，但需使用8位深度图片方能完美(Based on the matlab wavelet image noise reduction, pro-test debugging success, but need to use 8-bit depth images can only perfect)

设计一CQMFB，低通滤波器H_0 (z)来自一半带滤波器。该半带滤波器的长度为47，通带截止频率ω_p=0.42π，试给出H_0 (z)，H_1 (z)，G_0 (z)，G_1 (z)的幅频响应，单位抽样响应并画图。试着产生一信号，它由两个正弦加白噪声组成，一个在低频，一个在高频，正弦的频率及和白噪声的信噪比自己给定。试用所设计的滤波器组对该信号进行分解和重建。比较重建后的效果，并对结果继续进行分析。(Design a CQMFB, low pass filter H_0 (z) the half-band filter. The length of the half-band filter 47, passband cutoff frequency ω_p = 0.42π, try to give H_0 (z), H_1 (z), G_0 (z), G_1 (z) of the amplitude-frequency response, the unit sample response and Paint. Try to generate a signal that consists of two sinusoidal composition plus white noise, a low frequency, a high frequency in the signal to noise ratio, frequency and sine and white noise of its own given. Trial designed filter group that signal decomposition and reconstruction. Results were rebuilt, and the results continue to be analyzed.)

svm初始化函数，svm在计算中是需要提供的，很有用(SVM initialization function)

计算信号的双谱，为机械故障诊断提供依据，还可以用于故障特征提取(Bispectrum for calculating signals)
