RBF神经网络整定的PID控制，能以任意精度逼近任意连续函数(RBF neural network-tuning of PID control to arbitrary accuracy any continuous function approaching)

WINDOWS 下延时函数Sleep()以及for循环的测试程序, 死循环会使WINDOWS死机?怕是许多老程序员都未必知道.(Under WINDOWS delay function Sleep (), as well as for the cycle of testing procedures, will WINDOWS cycle crash death? Fear is that many programmers are not aware of the old.)

说明：  引入错误报告概率对协作检测的影响仿真程序(Influence Of Wrong Report In Cognitive Radio)

交织编码是一种信道改造技术，它通过信号设计将一个原来属于突发差错的有记忆信道改造为基本上是独立差错的随机无记忆信道。交织编码作为克服衰落信道中突发性干扰的有效方法，通常和其它用于纠正无记忆独立差错的信道编码相结合构成级联码，广泛应用于当代移动通信。(intertwined coding is a channel modification techniques, it will be designed to signal through an unexpected error originally belonged to the memory channel transformation is essentially independent of the random errors unmarked Recalling Channel. Coding intertwined as to overcome sudden fading channel interference effective way and the other is usually used to correct errors without memory of the independent channel coding combined constitute cascade code, Contemporary widely used mobile communications.)

matlab解偏微分方程，里面详细介绍了偏微分方程怎么离散化通过Matlab求解。(The MATLAB solution of partial differential equations)

两种控制方式的性能比较:模糊控制与PID控制(two ways to control the performance comparison : fuzzy control and PID control)

本程序是用matlab仿真软件和解析法来计算一维光子晶体带隙的另一个程序(this procedure is used Matlab simulation software and analytical method to calculate one-dimensional photonic bandgap of another program)

CPN网络，即对向传播网络，是将Kohonen特征映射网络与Grossberg基本竞争网络相结合，发挥各自特长的一种新型特征映射网络。(CPN network, the right to communication networks, Kohonen feature is the mapping of network and basic Grossberg competing networks combined play to their strong points of a new feature mapping network.)
