说明：  普林斯顿大学无线通信著名教授Verdu的经典代表作，绝对的好书！(Princeton University Professor Verdu wireless communications known classical masterpieces, absolute good book!)

gaussfilter in matlab

已知观测数据为A+W(n)，其中A为直流信号，W为复高斯噪声，服从CN（0， ），在统计N次下，计算X的统计平均值 ，求T(x)= 的pdf：p(T(x)|H0)、p(T(x)|H1)。 H0： W H1： A+W (Known observation data A+W (n), where A is the DC signal, W is the complex Gaussian noise, subject CN (0,), N times in the statistics, the calculation of the statistical mean of X, find T (x) = a pdf : p (T (x) | H0), p (T (x) | H1). H0: W H1: A+W)

将矩形图通过极坐标变换转换成笛卡尔坐标系上的圆形图(The rectangle by polar coordinates transformation into a cartesian coordinate system on the circular diagram )

1. 构造含噪音的振动信号 faultysignal_with_noise， 2. 利用小波变换 Wavelet transform去噪，小波包 Wavelet packet transform 变换去噪， 3. 把两种去噪后的信号，分别用STFT ,FFT ,小波变换三种方法进行错误诊断(1. the vibration signal faultysignal_with_noise, which contains noise, is constructed. 2. using wavelet transform Wavelet transform denoising, wavelet packet Wavelet packet transform transform de-noising, 3. the two kinds of denoising signals are diagnosed by three methods, STFT, FFT and wavelet transform respectively.)

说明：  这是一个matlab小程序,可用于求解微分方程,特别是抛物型的微分方程(Matlab This is a small program that can be used to solve differential equations, in particular the type of parabolic differential equations)

关于采样定理的验证的matlab程序，有利于理解带通采样(Verification sampling theorem on the matlab program that facilitates understanding bandpass sampling)

本程序用自然梯度算法实现源信号的分离，给出了平均串音误差(This program uses natural gradient algorithm to achieve the separation of source signals, and gives the average crosstalk error)
