Popis:	105 In recent years,the technology through in wireless communication is popular in the world.Especially,more and more people discussed the cooperative communication.The experts talked about the advantages that it is not only easy to achieve but also realize the diversity technology. This paper uses the Amplify and Forward relay to amplify the power for the destination receiving channel state information(CSI).S-R channel information will be quantified in relay and transmited to the destination in delicated channel.The destination receives the informations from the source and the relay by using maximal ratio combining.The paper simulates the SNR distribution and compares with the SNR distribution from each channel.Finally,the paper simulates level crossing rate and average fade duration in this paper.
