： 针对粒子群优化算法易陷入局部极值的缺点， 提 出一种改进粒子群算法， 该算法借鉴贪婪算法的思想初始化种群， 利用两 个种群同时寻优， 并将遗传算法中交叉和变异操作引入其 中， 实现种群间的信息共享。(I n a l l u s i o n t o p a r t i c l e s wa r m o p t i mi z a t i o n b ei n g pr on e t o g e t i n t o l oc a l mi n i mu m， a n i mpr o v e d p a r t i c l e s wa r m o pt i mi z a t i o n a l g o r it h m i s p r o po s e d． Th e a l g o r it hm dr a ws o n t h e t hi n ki ng o f t he g r e e d y a l g o r it hm t o i n i t i a l i z e t he pa r t i c l e s wa l- n 1 ． Two s wa r ms a r e u s e d t o o pt i mi z e s y nc h r o no u s l y， a nd c r o s s o v e r a n d mu t a t i o n o p er a t o r s i n g e n e t i c a lg o r i t h m a r e i n t r o d uc e d i n t o t h e ne w a l g o r it h m t o r e a l i z e t h e s ha r i ng o f i n f o r m a t i o n a mo ng s wa r l T i S ．)

delta modulation source code

用matlab编的计算传感器配置的有效独立法、模态置信因子的一些小程序(EI MAC)

主要用于实现基于TOA/AOA/RSS/QRSS的二维定位算法，用matlab程序实现，内附有注释(Mainly used to implement based on TOA/AOA/RSS/QRSS two-dimensional positioning algorithm, using matlab program, enclosing a Comment)

We see that HTH matrix is almost diagonal as the off diagonal elements are nearly zero. So we are getting exact estimation in case of PRN INPUT due to diagonality of HTH matrix. As seen that the unknown inpulse response ( h ) and estimated impulse response ( hth ) are coming out to be exactly same. The estimation even gets better for large N .as we get the HTH matrix perfect diagonal. So we come to know that we can estimate the unknown parameters exactly when PRN input is used.

说明：  HFSS学习示例，十分有用，简单易懂，值得拥有(Learning example, simple and easy to understand, very useful, it is worth having )

本程序是原始粒子群算法，对一个简单函数的优化，可用来与其他算法功能进行比较。(This procedure is the original particle swarm optimization, a simple function of the optimization function can be used to compare with other algorithms.)
