watterson信道matlab仿真,瑞利衰落。。。。(This example shows how to simulate High-Frequency (HF) ionospheric channels, based on the models described in Recommendation ITU-R F.1487. In particular, it shows how to simulate the general Watterson channel model, and other simplified channel models used in the quantitative testing of HF modems. It makes use of the Rayleigh multipath fading channel object and the Gaussian and bi-Gaussian Doppler structures from Communications System Toolbox.)

Window Shell扩展编程编程的相关例子，想学shell编程的朋友有福了！(Window Shell-programming related to the expansion of programming examples, want to learn shell programming blessed Friend!)

关于用matlab实现滤滤器中输入波形的采样点数(on using Matlab filter filter realization of the input waveform sampling points)

小电流接地选线基于测度分析方法的相关程序，已仿真(Small current grounding line analysis method based on measurement of the relevant procedures, has simulation)

常用软件包,可以保存,做为日常函数调用,比较通用(Commonly used software packages, can be preserved as a day-to-day function call to compare GM)

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。(Partial discharge test of the signal collected is often mixed with white noise, periodic interference signal removal. Here the use of commonly used wavelet db Series DB6 wavelet carried out in the 9-scale multiresolution decomposition, based on the energy characteristics of white noise to estimate the scale threshold size, the use of hard-value deal, after the remodeling.)
