But when two nodes communicate via relays, it is difficult to get the perfect channel information, so relays must estimate their forward channel and backward channel in order to amplify the data to the destination. We investigate the effect of channel estimation error, and design the LMMSE estimator to estimate the channels, and also we consider the multi-relays to assist the whole system for training and data transmission. We propose the SNR gap ratio, outage probability, and the BER simulations for the analysis. Simulation shows that when using multi-relays, it can mitigate the effect of channel estimation errors in all of the amplify-and-forward (AF) scenarios.

碩士 === 國立中山大學 === 通訊工程研究所 === 99 === Cooperative communications have received much attention recently, due to its ability to attain cooperation diversity. But when two nodes communicate via relays, it is difficult to get the perfect
channel information, so relays must estimate their forward channel and backward channel
in order to amplify the data to the destination. We investigate the effect of channel estimation
error, and design the LMMSE estimator to estimate the channels, and also we consider the
multi-relays to assist the whole system for training and data transmission. We propose the
SNR gap ratio, outage probability, and the BER simulations for the analysis. Simulation shows
that when using multi-relays, it can mitigate the effect of channel estimation errors in all of
the amplify-and-forward (AF) scenarios.
