optimum placement of DG

按照指定噪声系数和指定的FIR滤波器参数，模拟接收机接收信号过程(In accordance with the specified noise figure, the FIR filter parameters and the specified process of the reception signal, analog receiver)

小波包分析提取振动信号中的特征频率，包括最后计算压缩图像的峰值信噪比和压缩效果的源码,包括回归分析和概率统计。( Wavelet packet analysis to extract vibration signal characteristic frequency, Including the final calculation of the compressed image peak signal to noise ratio and compression of the source, Including regression analysis and probability and statistics.)

基于simulink的初级OFDM仿真模块(The primary OFDM simulation module based on simulink.)

语音增强谱减法程序，已经运行成功，效果明显(Spectral subtraction speech enhancement program has been run successfully, obvious effect)

说明：  dynamic time warping source code

说明：  包含Simulink在控制系统、人工神经网络中的应用(With Simulink in the control system, the application of artificial neural network)

小波分析、局部放电试验所采集的信号中往往混有白噪声、周期干扰信号去除。此处采用常用db系列小波中的db6小波进行9尺度的多分辨分解后，根据白噪声能量特性，估算各尺度的阈值大小，采用硬值进行处理，后进行重构。(Wavelet Analysis、Signal acquired partial discharge test is often mixed with white noise, periodic interference signal removal. Db series wavelet commonly used here in db6 9 scale wavelet multi-resolution decomposition, according to the energy characteristics of white noise, the estimated size of each scale thresholds, hard-value processing, after reconstruction.)

说明：  实现两个指数信号的卷积，通过绘制出两个输入的指数信号的图形进行卷积后的图形说明卷积的作用。(Convolution of two exponential signals to achieve, by drawing out the index of the two input signals after convolution graphics graphic illustration of the role of convolution.)
