mean-filter1

As digital computers cannot generate true random numbers. So a pseudo random number generator must have uncorrelated sequences, long period, uniformity and efficiency. ‘myrand.m’ has pass the chi square test for uniform distribution.

说明：  毫米波图像超分辨复原，采用基于最大似然函数的算法，实现频谱外推(Millimeter wave image super-resolution restoration, using an algorithm based on maximum likelihood function, the spectrum extrapolation)

利用自相关法，计算基音周期，结果给出对应的时间值坐标。(The pitch period is calculated by the autocorrelation method, and the corresponding time value coordinate is given.)

模拟启闭载波信号的最佳接收机的情形,包含信号的产生,模拟调制,接收检测,并分析显示出实际和理论的误码率vs SNR,希望对大家有用！(carrier signal simulation includes the best receiver situation, including the selection of signal, analogue modem, receive detection, and analysis show that the practical and theoretical error rate vs. SNR, we want to help!)

matlab下对pcm编码进行模拟.可以进一步帮助理解编码过程(right pcm Matlab simulation code. Can help further understanding of the encoding process)

对信号进行内插处理，有16个复信号：1~16Hz；内插I=16 ；内插前采样率50Hz；滤波器265阶 。(Interpolation processing signal 16 multiplexed signals: 1 Hz to 16 Hz interpolated I = 16 before interpolation sampling rate of 50Hz filter 265 order.)

MFSK在加性高斯白噪声信道下的MATLAB仿真(MFSK simulation, Coherent and non coherent detection including performance with awgn)

This is matlab code for SVD based image watermarking

说明：  matlab GUI教程，是我在网上花钱买来的 很适合广大研究者(tutorial matlab GUI, I bought online to spend money very suitable for the majority of researchers)
