gammatone滤波器，模拟人耳的滤波功能，处理由麦克风接收到的声音信号，获得其特征参数。(gammatone filter to simulate the human ear filtering, processing the received voice signal from the microphone to obtain the characteristic parameters.)

信道编码仿真模型 汉明码 RS码 BCH码(Simulation model of channel coding)

sampencandApEn.m 为证明 样本熵 较 近似熵 更准确的程序 fast_ApEn1.m sampenc.m 为sampencandApEn.m的子程序(sampencandApEn.m sample entropy to prove more accurate than the approximate entropy procedure 3.fast_ApEn1.m sampenc.m subroutine is sampencandApEn.m)

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.)
