CG、Gauss、SOR、Jacobi迭代法matlab程序 自己收藏的源程序(CG, Gauss, SOR, Jacobi iteration method matlab program his collection of source code)

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.)
