设计了一个扩频 系统，具有扩频解扩的功能。系统中采用的是瑞利衰落的信道。仿真的结果很好，系统的误码率很小(Designed a spread-spectrum system with spread spectrum despreading function. System is used in the Rayleigh fading channel. Good simulation results, the system bit error rate of the small)

THIS CODE REMOVES "SALT AND PEPPER NOISE" BY AVERAGING.MAY HELP BEGINNERS TO UNDERSTAND THE COLOR PICTURE AND REMOVING THE NOISE IN GREY IMAGE OUTPUT OF GIVEN COLOR IMAGE.

sdm pll，数据转换器中的SDM仿真(sdm pll，data conventor sdm simulate)

利用lms算法，实现回波抵消，消除回声信道返回的噪声信号。(Least means squares (LMS algorithm, realize the echo offset, eliminate the noise signal back to the echo channel.)

对256×256大小的8bit灰度lena图像进行仿真计算，稀疏矩阵采用DCT矩阵，观测矩阵采用高斯随机矩阵，重构算法采用OMP（正交匹配追踪）算法。 (256256 size 8bit grayscale lena image simulation, sparse matrix DCT matrix, and observation matrix using Gaussian random matrix reconstruction algorithm using OMP (orthogonal matching pursuit) algorithm.)

这是在matlab下实现的包络检波算法。先对信号进行调制，然后进行包络检波。(This is achieved under matlab envelope detection algorithm. First signal modulation, and then proceed to the envelope detector.)

说明：  利用小波包变换对一个二维含噪图像进行分析处理。(using wavelet transform packets of a two-dimensional images with noise analysis.)
