signals snr ratio by opertions

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)

说明：  带残差模型灰色预测模型.GM(1,1),残差,matlab(The grey prediction model with residual error model )

基于导频的频偏估计算法，经典Classen算法，亲测课实现(Frequency Offset Estimation Algorithm Based on the pilot, classic Classen algorithm, pro-test lesson realization)

主要是对测井资料进行分析，要对数据数字化之后进行，而且采样间隔一定(log Processing)

GPS的pn码捕获matlab仿真程序，通过序列相关实现捕获功能(GPS-pn code acquisition matlab simulation program, through the serial correlation realize capture)

说明：  给照片加相框，相框的边界可根据照片的尺寸自动调节，支持灰度和彩色jpg照片。(This code frames images with a beautiful frame. Automatically adjusts the bordering i.e. framing according to the image s dimensions. Works for both colored and gray images. )

this is genaral techniques involves in noise cancellation and this matlab version
