通过选择展开的基函数进行信号Gabor展开(Decompose Signal by Gabor Transform)

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)

当文件的某一行存在某一个字符串时，就删除该文件的那一行，并适应于多文件的批量处理。(When a file on a row exists a string, delete the line of the file, batch processing and is suitable for multiple file.)

介绍matlab中GUI的学习知识，值得对于matlab有兴趣的爱好者参考学习，我也在学习当中，还不错(Introduced in GUI matlab learning knowledge, it is worth for matlab interested enthusiasts refer to learning, I am also learning, good)

压缩感知入门程序，让你快速掌握压缩感知的基本思路(the fundamental of compressive sensing, you can understand the compressive sensing this code.)

常胜将军 :在计算机后走的情况下，要想使计算机成为“常胜将军”，必须找出取 关键。根据本题的要求枷以总结出，后走一方取子的数量与对方刚才一步取子的数量之和等于，就可以保证最后一个子是留给先取子的那个人的。(Ever Victorious General: On the computer where to go, in order to make the computer become " Ever Victorious generals" must be taken to find the key. According to the requirements of this title thoughts to conclude that one party to take the child away after the number of step with each other just to take the child and is equal to the quantity, we can ensure that a child is left to the first final to take the child of that individual.)
