通过锁相环的方法实现2fsk的传输系统的设计，，这是仿真图。。仅供参考(Achieved through the PLL 2fsk designed transmission system, which is the simulation of Fig. . For reference only.)

多通道盲卷积实现图像超分辨率重建 效果不错 (Blind convolution multiple images super-resolution)

本程序主要进行两个时间序列的互相关计算。可用于信号降噪分析。(This program mainly carries out the cross correlation calculation of two time series. It can be used for signal noise reduction analysis.)

将声音文件在时间轴上分割成几段，分别将段的秩序及某些段内的秩序颠倒，从而实现了对声音文件的加密。首先，先读取一个声音信号，对信号做1024点FFT变换，取完点之后，分成四个向量，四个向量组成一个矩阵，再对每一个向量进行转置，再重新整合，从而就实现了回密的过程。(Sound files on the timeline will be divided into paragraphs, each paragraph of the order and reversed the order of some paragraphs to realize the encryption of sound files. First, the first reading of a voice signal, the signal was 1024 points FFT transform, check after the completion point, divided into four vectors, the four vectors form a matrix, then for each vector transpose, re-integration, which will achieve a return to close the process.)

本程序是EM算法，是参数估计（极大似然估计）方法的数值解法。(This procedure is the EM algorithm, is the parameter estimation (MLE) method of numerical solution.)
