rapresents AR(1) model. dsp and correlation funtion of the ar(1) MODEL. it uses randn to generate vector and filter to do ar(1).

说明：  matlab写的运动检测 自动实现 十分有用的代码 值得学习！(Motion detection matlab automatically write the code should be very useful to learn!)

一个OFDM符号128个有效符号，插入128个虚拟子载波 符号率（即有效数据率）fsymbol，而发送速率（需要包括虚拟子载波）2fsymbol 输入的数据需要2倍的发送数据率，以便进行内插，实现位定时跟踪，即4倍fsymbol采样率的调制信号 OFDM symbol Nfft=128 points 一个OFDM符号数据点 Nfft*2 = 256 ， Guard Interval点 ＝Ng*2=64 (128 of an OFDM symbol of a valid symbol 128 inserted virtual sub-carrier Symbol rate (the effective data rate) fsymbol sending rate (including virtual subcarriers) 2fsymbol Of the input data needs to be 2 times the transmission data rate, in order to carry out the interpolation, to achieve the bit timing tracking, i.e. four times the sampling rate modulation signal fsymbol OFDM symbol Nfft = 128 points One OFDM symbol data points nfft* 2 = 256, the Guard Interval dot = Ng* 2 = 64)

DCT变换：变换域系数选取采用阈值编码，：阈值越小，图像恢复效果越好，但压缩效果差，一般取在5-10 即可很好的获得恢复图像信息。(DCT transform: transform domain coefficients selected using the threshold coding: the smaller the threshold value, the better the image restoration, but the compression is poor, and generally in the 5-10 to get a good recovery image information.)

说明：  forward处理程序，使用于煤炭、石油、天然气行业(forward processing procedures used in coal, oil, gas industry)

说明：  通信系统的仿真,CRC是纠错码的一种,可以用于通信领域,本例子给出了基于matlab的程序,可用于实际的仿真!(communications system simulation, CRC is an error-correcting code that can be used in communications, this example is based on the Matlab program can be used for actual simulation!)
