In this paper, we investigate the performance of adaptive modulation in spectrum sharing cognitive relay networks, where the secondary user (SU) transmits the message by one best relay with amplify and forward (AF) relaying scheme. Moreover, to guarantee the primary user (PU)'s transmission quality, the interferences caused by the SU transmitter and the selected relay are less than a predetermined...
According to the characteristics of meteor burst channels, variable rate data transmission is often employed to improve the average system throughput, and the time-varying meteor channel in the presence of multi-path rays brings difficulties in both data detection and channel estimation at the receiver. As we know, per-survivor processing (PSP) based on the joint data and channel estimation of maximum...
