分析并实现了跳频信号的检测方法，用程序给出仿真结果(Analysis and implementation of frequency hopping signal detection method, using the program simulation results)

说明：  用于提取信号的时频域特征参数，比如信号均值、方差、以及一些无量纲的时域特征参数(Time-frequency domain characteristic parameters used to extract signals, such as signal mean, variance, and some dimensionless time domain characteristic parameters)

0-1整数规划有很广泛的应用背景，比如指派问题，背包问题等等，实际上TSP问题也是一个0-1问题，当然这些问题都是NP问题，对于规模较大的问题用穷举法是没有办法在可接受的时间内求得最优解的，本程序只不过是一个练习，得意之处是用递归法把所有解都排列出来。另：胡运权所著的《运筹学基础及应用（第三版）》第97页的例3，我用本程序求解得到的结果是：最优解是x*=(1,0, 0, 0, 0)，最优值是f(x*)=8，但书求得最优解是x*=(1,0, 1, 0, 0)，最优值是f(x*)=4，是不是书中写错了，请大家验证。以下是源程序，大家可以任意使用无版权问题，另外，如果大家有大规模的0-1规划的问题也希望提供给我，谢谢。变量个数至少是3个(0-1 Integer Programming is a very broad background, such as assignment, bags and so on. actually TSP is a 0-1, of course, these problems are NP, for larger problem with the law is not exhaustive approach in an acceptable time frame to obtain the optimal solution. this procedure is only one practice, farewell tour is the method used recursive all of the solutions to show. Another : Hu Yun-author of "operational research, and application base (third edition)" Article 97 of the three cases, I use this procedure to solve the result is : is the optimal solution x = (1,0, 0, 0, 0), the optimal values of f (x*) = 8, but the book is to find the optimum solution x = (1,0, 1, 0, 0), the optimal values of f (x*) = 4, the book is not a mistake, please certification.

OFDM系统的MTLAB程序仿真，对于刚入门学OFDM的新手来说很有帮助(OFDM system MTLAB process simulation, for the novice just started learning it was helpful for OFDM)

Fisher是多元统计分析的常用的方法之一，判别分析方法可在各种领域得到应用。一般用于确定属于一个可观测量是什么类型。(Fisher method is one of the common methods of multivariate statistical analysis, discriminant analysis method can be applied in various fields. Usually used to determine what type of a observables belonging.)
