QPSK信号通过瑞利衰落信道后的误比特率和误符号率，并与AWGN信道下的误比特率和误符号率进行对比。其中，多普勒频移为 100Hz，经过矩形脉冲成形后的抽样时间间隔为1/800000s。(The QPSK signal harms the bit rate after the Rayleigh fading channel and harms the mark rate, and harms the bit rate with the AWGN channel under and harms the mark rate to carry on the contrast. And, the Doppler shift is 100Hz, after undergoing the square pulse forming the sampling time gap is 1/800000s. )

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.)
