matlab 经典算法程序 解方程，一些常用的经典算法，简单实用(classical algorithm matlab program solve the equation)

ALOHA协议的思想很简单，只要用户有数据要发送，就尽管让他们发送。当然，这样会产生冲突从而造成帧的破坏。但是，由于广播信道具有反馈性，因此发送方可以在发送数据的过程中进行冲突检测，将接收到的数据与缓冲区的数据进行比较，就可以知道数据帧是否遭到破坏。(ALOHA protocol s thought is very simple, as long as the user data to be sent, although let they send. There are, of course, such conflicts which cause the destruction of the frame. But, because the radio channel has feedback, so the sender can be tested to the conflict in the process of sending data, the received data comparison with data of the buffer, you can know whether data frame was damaged.)

VC_和Matlab混合编程在图像处理中的应用(VC_ and hybrid programming in Matlab Image Processing)

说明：  这是一个用matlab辅助图像处理源代码(This is an assisted image processing using matlab source code)

此程序是用来读取C版本星历文件并进行拟合预推处理的，简单可用(the program is used to read C version ephemeris , couple and predict, it is easy and useful)

共轭正交镜像滤波器组的设计。令N=22,wp=0.45pi,用切比雪夫最佳一致逼近法设计单带滤波器G(z),在得到半带滤波器Hlf(z). (conjugate mirror filters orthogonal design. Order N = 22, wp = 0.45pi. Chebyshev with the best approximation consistent single-band filter design G (z), with the half-band filter Hlf (z).)

麻省理工学院introduction to matlab课程作业指导，包含matlab实例（3），相互交流(same as before excellent matlab exercises homework for improving matlab )

这是《Space-Time Codes and MIMO Systems》书中第二章的源程序，包括mimo信道模型，遍历容量，中断容量以及发射端或接受端具有相关性等程序。(This is the " Space-Time Codes and MIMO Systems" source book, the second chapter, including mimo channel model, ergodic capacity, the outage capacity and the transmission side or the receiving end of relevant procedures.)

these programs includes sorce codes
