NW小世界网络的构成原则为：从一个环状的规则网络开始，网络含有N个结点，每个结点向与它最近邻的K个结点连出K条边，并满足N>>K>>In(N)>>1。随后进行随机化加边，以概率p在随机选取的一对节点之间加上一条边。其中，任意两个不同的节点之间至多只能有一条边，并且每一个节点都不能有边与自身相连。改变p值可以实现从最近邻耦合网络(p=0)向全局耦合网络(p=1)转变。在p足够小和N足够大时，NW小世界模型本质上等同于WS小世界模型。 (NW constitutive principles of small-world networks: from the rules of a ring network, network with N nodes, each node is connected to the K node with its nearest neighbor K edges, and meet N > > K > > In (N) > > 1. Followed by randomization into the plus side, with probability p with an edge between a pair of nodes in a randomly selected. Wherein between any two different nodes at most only one edge, and each node can not have a side connected with itself. P value can be changed to achieve the transition from the nearest neighbor coupling network (p = 0) coupled to the global network (p = 1). When p is small enough and large enough N, NW small-world model is essentially the same as the WS small-world model.)

基于matlab的bpsk的调制 随机信号和载波可根据需要改动(Based on the bpsk matlab modulation random signals and carrier may need to change)

利用matlab编写的rake接收机的程序以及报告~对初学者学习rake接收机很有帮助！！！(Rake receiver matlab prepared using the procedures and reporting ~ rake receiver is very helpful for beginners! ! !)

该程序可以实现图片的拖拽，放大和缩小等简单的处理。(The program can drag images, zoom in and out such simple treatment.)

该程序是使用Matlab仿真协同通信的DF（解码转发）基本性能，基本模型S-R-D三个节点，接收端使用MRC（最大比合并）。固定DF由于SR信道的错误，其性能受到限制，在大SNR情况下不能获得有效分集。而当SR距离足够近的时候，可能获得一定的分集增益。(The program is a cooperative communication using Matlab simulation DF (decode forwarding) basic performance, the basic model of the SRD three nodes, the receiver uses the MRC (maximum ratio combining). Fixed DF error of the SR channel, its performance is limited, can not obtain a valid diversity in the large SNR case. When the SR close enough, you may get some diversity gain.)

电力电子变换器采用重复控制策略。在反馈回路中设置一个内部模型，使该内部模型能够很好地描述系统外部信号特性，通过该模型的作用可使系统获得理想的指令跟踪特性，具有较强的扰动抑制能力。(Repetitive Control Strategy for Power Electronic Converter.An internal model is set up in the feedback loop, which can describe the external signal characteristics of the system well. Through the function of this model, the system can obtain ideal command tracking characteristics, and has strong disturbance rejection ability.)
