首先根据短训练字的特性进行相关运算，进行信号到达检测，当检测到相关值大于门限一定次数后，认为有信号到达。然后根据长训练字的特性，进行相关运算，进行OFDM符号FFT窗口起始位置的估计。估计出FFT窗口的位置后，先在时域进行小频偏的估计，将两个长训练字进行小频偏补偿后，进行FFT运算，根据FFT运算的结果进行整数倍频偏的估计。这些参数估计完成后，就可以进行数据解调了。先对数据部分进行完整的频偏补偿，然后根据估计的FFT窗口位置进行FFT运算得到频域的数据，进行解调。然后在对应于导频的子载波位置上提取出导频信息，根据导频信息估计出剩余定时误差以及剩余的信道响应误差，将误差量送入环路进行跟踪。当收到所有数据后，重新回到信号到达检测状态，进行下一次信号到达的检测和信号接收。(First, according to the characteristics of the short training word correlation operation, the signal reaching the detector, when the detected correlation value is greater than the threshold after a certain number of times that a signal arrives. And then the characteristics of long training word, the correlation operation for the FFT window starting position of an OFDM symbol estimate. The estimated position of the FFT window, the first small frequency offset in the time domain estimation, the two long training word small frequency offset compensation, the FFT operation, the FFT result of the operation for integer frequency offset estimate. These parameter estimation is completed, the data can be demodulated on. The first portion of the data for a complete frequency offset compensation, and based on the estimated FFT window position of the FFT operation to obtain frequency domain data, demodulated. Then corresponding to the position of the pilot subcarriers are extracted on pilot inform)

依据JPEG压缩标准的算法，对lena图像进行压缩，并恢复出原始图像，然后对照原始图像，对恢复出的图像进行客观评价：计算峰值信噪比PSNR及均方误差MSE。(language matlab jpeg picture compress)

说明：  该程序通过模仿生物的遗传特点，解决全局最优解的问题(The program solves the problem of global optimal solution by imitating the genetic characteristics of organisms)

matlab需要那么复杂的多重积分,实在没办法才考虑使用.一般来说,积分中带有参数,无论是被积表达式或者说积分限都是相当麻烦的,求解消耗的时间非常多.............数值积分才是解决问题的通法,可以自己调节精度~(it is good. If you visited Indianapolis you would be able to find your way around easily because most of the streets corss each other like a chessboard(棋盘). In the center of the city, called the Circle, stands the Soldiers and Sailors’Monument, 100 Meters high. Also in the center there are many buildings made of the famous Indiana stone, which makes them white in color.)
