关于QPSK调制的仿真，再Matlab中间但实现QPSK的调制。(QPSK modulation on the simulation, and then between Matlab but realize QPSK modulation.)

For a given source vertex (node) in the graph, the algorithm finds the path with lowest cost (i.e. the shortest path) between that vertex and every other vertex. It can also be used for finding costs of shortest paths from a single vertex to a single destination vertex by stopping the algorithm once the shortest path to the destination vertex has been determined. For example, if the vertices of the graph represent cities and edge path costs represent driving distances between pairs of cities connected by a direct road, Dijkstra s algorithm can be used to find the shortest route between one city and all other cities. As a result, the shortest path first is widely used in network routing protocols, most notably IS-IS and OSPF (Open Shortest Path First).

主要讲述如何利用matlab进行建模和仿真，都是一些基础知识，适合初学者(Mainly on how to use matlab for modeling and simulation, are some of the basics for beginners)

这是我们参加深圳杯2012年D题的打孔机生产效率的问题，希望对大家有帮助。这可是很强的东西。(This is our participation in Shenzhen Cup 2012 theme punch D productivity problem, we want to help. This is strong stuff.)

利用matlab实现下面的问题：其中u(k)和z(k)分别为模型的输入和输出变量；v(k)为零均值、方差为1、服从正态分布的白噪声；为噪声的标准差；利用得到的u(k)和z(k)来辨识模型的阶次和参数。　　(Using matlab to achieve the following questions: where u (k) and z (k) respectively, the input and output variables of the model v (k) with zero mean and variance 1, follow a normal white noise noise standards Poor utilization u (k) and z (k) to identify the order and parameters of the model.)

智能天线技术，里面介绍了很多关于频域宽带波束形成方面的算法。作者L.C Godara是这方面的大牛，发表了很多关于波束形成方面的paper，大家可以参阅一下。(Smart antenna technology, which introduces a number of algorithms on the frequency domain broadband beamforming aspects. The Author LC Godara large cattle in this area, published a paper about the many aspects of beam forming, we can see it.)

这是周建兴的《matlab从入门到精通》第6章的所有源代码，都可以运行的出来，和课本上的一样，(This is Zhoujian Xing' s " matlab from entry to the proficient," Chapter 6, all the source code, you can run out, and textbooks on the same)
