这是一个EEMD 分解的程序，可以用在故障诊断中，可以运行(This is a EEMD decomposition program that can be used in fault diagnosis, you can run)

這是一個利用butter filter 的bandstop 來濾除原始訊號中有雜訊的方法，先轉為spectrogram觀察雜訊所分步頻帶與能量，再依照要濾除的部分作bandstopa(This is a use of bandstop butter filter to filter out the noise of the original signal has a method, the first step into a spectrogram observation noise and energy of the band, then follow to filter out parts for bandstopa)

下载的几个ofdm程序，基本是频偏估计相关的，打包在一起了(Download ofdm program, the basic frequency offset estimation, packaged together)

输入信号为方波信号+高斯白噪声，方波信号基 频为1kHz，幅值为1，高斯白噪声方差为0.2， 均值为0，采样频率为20kHz。试用周期图法和 ARMA谱估计法(SVD-TLS)估计此信号的功率 谱，并分析比较其结果(The input signal is a square wave signal+ Gaussian white noise, square wave signal fundamental frequency 1kHz, amplitude is a Gaussian white noise variance is 0.2, the mean is 0, the sampling frequency is 20kHz. Try periodogram and ARMA spectral estimation method (SVD-TLS) estimate the power spectrum of this signal, and the analysis and comparison of the results)
