相空间重构及奇异值分解代码，可用于消噪处理，希望有所帮助(Phase space reconstruction and singular value decomposition code, can be used to eliminate noise processing, Hope that helps)

关于光流法的一个外文论文，很好的讲述了光流法算法(An optical flow method on foreign language papers, very good about the optical flow algorithm)

There is a trend to develop blind or semi-blind source extraction algorithms based on second-order statistics, due to its low computation load and fast processing speed. An important and primary work is done by Barros and Cichocki, who propose an extraction algorithm based on a time delay. The algorithm is simple and fast, but its performance is not satisfying. The paper extends their work and proposes a robust algorithm based on eigenvalue decomposition of several delayed covariance matrices. It is faster and has better performance, which is conˉrmed by theoretical analysis and computer simulations.

FSK调制解调器CMX469程序，实测可用(FSK modem CMX469 program, the measured available)

本文主要讲的是图像变化中所使用的小波变换的一些基本知识(This article is primarily concerned with changing the image used in some of the basics of wavelet transform)

说明：  这个程序和我上传的上一个程序有关，它可以将上个程序收集到的频谱数据进行拼接，从而在全频段进行展示，还能计算频谱上的信号频谱带宽和频点 主要参数 start_freq %扫频中心频率fc的起始频率， stop_freq %扫频中心频率fc的截止频率 rtlsdr_fs %每一次扫频的采样频率，改变他会影响每次扫频的带宽 nfrmhold %每次扫频的帧数 nfft %fft点数 overlap %扫频频谱的重叠率(dataspecrumcatch, catch the spectrum and It can also calculate the signal spectrum bandwidth and frequency point on the spectrum)
