The thesis mainly studies the problem of forwarding strategy in collaborative system.Some strategies,such as amplify-and-forward and decode-and-forward,are used in communication,which improve the communication system capacity..But the two strategies have the problems of magnifying the noise signal synchronously and being easy to misjudge signals.Through improving the average bit error rate of coordination system,in the condition of additive white Gaussian noise channel,it deduces the theory and simulation analysis of the two strategies' average bit error rate.This paper presents an improved forwarding strategy algorithm which is a new hybrid collaborative forwarding strategy based on feedback information.The experiment shows that the new hybrid collaborative forwarding strategy has the advantage of the two strategies,overcomes the shortcoming of misjudgement,improves the average bit error rate of collaborative system compared with the amplify-and-forward or decode-and-forward,and provides theoretical basis for practical design.
