there is a main program with a lot o code for this site

this is the research doc for mp3 stegnography

1998年, Watts和Strogatz 提出了小世界网络这一概念,并建立了WS模型。 实证结果表明,大多数的真实网络都具有小世界特性(较小的最短路径) 和聚类特性(较大的聚类系数) 。 WS小世界模型构造算法 1、从规则图开始：考虑一个含有N个点的最近邻耦合网络，它们围成一个环，其中每个节点都与它左右相邻的各K/2节点相连，K是偶数。 2、随机化重连：以概率p随机地从新连接网络中的每个边，即将边的一个端点保持不变，而另一个端点取为网络中随机选择的一个节点。其中规定，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。 (In 1998, Watts and Strogatz proposed the concept of the small world network, and the establishment of the WS model. The empirical results show that most real networks have small world (the smaller the shortest path) and clustering properties (high clustering coefficient). WS small-world model construction algorithm 1, from the rules FIG: consider a nearest neighbor coupling network with N points, they are surrounded by a ring, wherein each node and its left and right adjacent to each of K/2 connected to the node, K is an even number. The 2 randomized reconnection: randomly with probability p from the new connection on each side of the network, coming section of one of the endpoints remain unchanged, while the other endpoint is taken as the random selection of a node in the network. Which states that between any two different nodes can have at most one edge, and each node can not be connected to its own side.)

说明：  进行多目标优化，主要是使用了NSGA-2的算法，在代码中进行了必要的标注(In the process of multi-objective optimization, nsga-2 algorithm is mainly used and necessary annotation is made in the code)

利用MATLAB和VC共同开发的信号处理程序。(Using MATLAB and VC joint development of signal processing.)

信道编码，用于信号在信道中安全传输，抵抗高斯噪声等干扰攻击。(Channel coding, for the secure transmission of the signal in the channel to resist attack Gaussian noise interference.)

2D fdtd with pml and two sinosudoal point source

In image processing, probably the most familiar is the image brightness and contrast adjustment

说明：  NOMA的吞吐量的计算，可以正确计算出结果。实测有效。(The throughput of NOMA can be calculated correctly. The measured results are effective.)
