Gauss Filtering Method to find impulse response and many other property

说明：  IIR低通滤波器，matlab与verilog程序完全对应(iir low pass filter matlab result fully match the verilog output.)

布朗运动的MATLAB模拟，动态图形的一个简单学习例程。txt文件，粘贴到matlab中就可以运行。(The MATLAB simulation of the Brown movement, a simple learning routine for dynamic graphics. Txt files, paste into the Matlab can run.)

主要就是实现L_M优化算法，用matlab写的 转成c该很容易的，用来仿真用的，希望大家给出点意见，第一次上传(err)

自己写的一个OFDM发送接收的程序，注释详尽，适合初学者，有图形验证。可实现IFFT过采样，以及prefix(Writing their own to send an OFDM reception process, detailed notes, suitable for beginners, there is graphical verification. Can achieve over-sampling IFFT and prefix)

小波变换进行变速箱故障诊断 首先将s1和s2信号时域谱（s1代表维修前的振动信号，s2代表维修后的振动信号），画出来进行对比，会发现s1信号的振动幅值会比较高；然后对s1和s2分别进行小波分解并画出各层的时域谱，只对比s1和s2分后的最高时域谱，s2更加的具有周期性，且幅值较小，s2周期性不够明显，且振动过于密集。分析完时域谱后开始分析频谱，首先对原信号s1和s2fft转换，得到频谱图，如图，然后再对小波分析后高频部分进行fft转换，做出频谱图。对比后我们发现，在f 2375HZ出（也就是齿轮的啮合频率），s1信号频谱幅值会有急剧的升高，然后，其谐波的幅值也会增大。所以可以推断出该维修前的增速箱的齿轮可能出现问题。(Gearbox fault diagnosis based on wavelet transform s1 and s2 first time domain signal spectrum (s1 behalf of the vibration signal before maintenance, vibration signal s2 representative of repaired), drawn comparison, you will find a signal s1 vibration amplitude will be higher then s1 and s2 respectively wavelet decomposition and draw the layers of time-domain spectrum to only a maximum time domain spectroscopy s1 and s2 points after, s2 is more cyclical and smaller magnitude, s2 cyclical enough obviously, and the vibration is too dense. End domain spectral analysis after the beginning of the spectrum analysis, the first of the original signal s1 and s2fft conversion to give the spectrum, as shown, and then after the high frequency part of wavelet analysis fft transformation to make spectrum. We found that after the comparison, at f 2375HZ out (i.e. the gear mesh frequency), there will be a sharp increase in the amplitude spectrum of the signal s1, and then, the amplitude of the ha)
