This folder contains several codes which are about energy detector.

本实验设计了一个《北京、南京、深圳列车查询系统》的图形用户界面。用户可以通过此界面，采用“按车站名称查询”、“按列车车次查询”和“按出发地—目的地查询”三种方式，方便地查询需要的列车信息。界面友好清新，操作方便。(The experimental design was a " Beijing, Nanjing, Shenzhen Train Enquiry System," the graphical user interface. Users can use this interface, a " query by station name" , " Query by Train Train" and " by origin- destination query" three ways to easily check in need train information. Fresh and friendly interface, easy to operate.)

用MATLAB实现加噪信号的消噪,用了三种常用方法。(de-noise programme by MATLAB，it is very useful for newerws.)

低通抽样定理程序有课程设计的有需求的自己(Low-pass sampling theorem of the curriculum design process there is a demand of their own)

基本的PSO程序，可以直接运行。希望大家喜欢。(basic PSO)

用于计算分析无源定位中TDOA的定位精度，画出了GDOP图(Used to calculate and analyze the positioning accuracy of TDOA in passive location, and draw the GDOP graph )

（7,4）汉明码的编译码代码，可以作为参考((7,4) hamming code encoding and decoding the code, can be used as reference)

A useful wrapper over the boost Mersenne Twister random number generator. It is implemented as a singleton such that the same instance can be used throughout a code by requesting the singleton instance. It also can return the host rng for boost functions that requires it. A unary function is also provided for use with std::random_shuffle for example.
