Harmonic Product Spectrum

bpsk的各种代码，有高斯白噪声下的(BPSK various codes, have under the Gaussian white noise)

FIR低通滤波器设计，运行通过，通过改变滤波器参数，可以得到不同阶数的滤波器，加有随机噪声的语音信号通过滤波器后会有很大改善。(FIR low-pass filter design, to run through, can be obtained by varying the filter parameters, the number of filters of different orders, and added with the random noise of the speech signal through the filter will be greatly improved.)

MATLAB潮流计算(MATLAB flow calculation)

说明：  　本文在简要介绍了MA TLAB 和BP 网络的基 础上, 详细论述了在MA TLAB611 中, 如何利用其提供的神经网络工具箱实现BP 网络的设计, 最后给出了一个BP 网络的设计实例。 (This paper briefly introduced the MA TLAB and BP network based on the detail in the MA TLAB611, how to use its neural network toolbox provided realize the design of BP network, and finally gives a design example of BP network.)

文中的方法是把图像分块，小波分解得到低频分量、高频分量，然后计算每一块的对比度，把图像块划分为清晰块、模糊块，把清晰块和模糊块相邻的区域定义为边界区域，融合时，直接选取清晰块作为融合后的相应块，对于边界区域，在小波分解的基础上采用基于对比度的像素选取的方法进行处理。(Paper, the method is to image segmentation, wavelet decomposition are low frequency, high frequency components, then calculate the contrast of each piece, the image block is divided into clear blocks, fuzzy block, to clear blocks and fuzzy block is defined as the border region adjacent to area, integration time, a clear block directly select the corresponding block as a fusion, for the border region, the wavelet decomposition on the basis of the pixel-based contrast method selected for processing.)

微分进化算法matlab程序代码，可直接运行，给研究微分进化算法的朋友提供帮助(Differential evolution algorithm)

对肌电信号中的有用信号的提取，将无用信号幅度变为0.(Useful for EMG signal extraction in the unwanted signal amplitude becomes 0.)

说明：  实现资料预测，输入训练集数据和测试集数据可以得到对应的均方根误差(Realization data prediction)
