关于流通渠道中生产商与零售商关系的博弈分析(A Game Analysis about Relationship between Manufacturer and Retailer in Circulation Channel )

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)

基于matlab7.0,德尔菲大学的源代码，遗传算法工具箱(targetalloc)

matlab编写的多目标处理程序，里面包括IMM，JPDA等各种算法，对于学习信息融合的同学肯定有帮助(matlab prepared to deal with multi-objective process, which include IMM, JPDA, such as a variety of algorithms, information fusion for the study will certainly help the students)

说明：  搭建切换系统的模块，很有用的哦,在此基础上很容易搭建时滞系统的仿真模块哦，还可以提出宝贵的意见修改哦(it is very useful for you to simulation a switched system)

這是一款好用的 streaming 軟體，重點還是免費的(This is good for streaming software, the focus is still free)

将两个矩阵的卷积运算转换为构造的新矩阵的相乘运算(The two matrix of convolution operation into the matrix multiplication)

The function takes three input arguments (function and two initial guesses belonging to the interval). After iterations, it returns the root of the function. The fourth input argument is to change the stopping criteria of the loop.
