说明：  用matlab中的FFT函数实现了正弦信号，矩形信号，和白噪声的频谱分析(FFT with matlab function in a sinusoidal signal, the rectangular signal, and white noise spectrum analysis)

跑检距时距曲线，时距曲线，跑检距，平局速度的时距曲线与均方根速度的时距曲线比较(Run inspection from the time-distance curve, time-distance curve, running offsets, draw speed when away from the curve and the rms velocity-distance curve)

声线图，找的，可以看看，比较简单，可以用一下(shengxiantu，is found by me)

这是关于扩频的一些基本知识,希望能对大家有帮助.(this is about spreading some basic knowledge, we want to help.)

这个是我的毕业设计做的我觉得对大家还是有写用的，所以我给打击看看希望大家也给点意见。(this is my graduation design so I think people are still used to write, So, I hope to see you blow also points.)

生成m序列，通过输入本原多项式的系数来自动实现。(M sequence generated by the primitive polynomial coefficients input automatically.)

LMS自适应均衡算法，对于学习现代数字信号处理的朋友们很有参考价值(LMS adaptive equalization algorithm )

视频背景非参数估计论文及matlab实现.matlab代码只实现了灰度图的背景估计，论文利介绍的彩色视频处理方法可以自己看看怎么做。(Background and Foreground Modeling Using Nonparametric Kernel Density Estimation for Visual Surveillance AHMED ELGAMMAL, RAMANI DURAISWAMI, MEMBER, IEEE, DAVID HARWOOD, AND LARRY S. DAVIS, FELLOW, IEEE Invited Paper )
