Cooperative OFDM systems for UWAC with SNR-based relay selection schemes
Karakaya B.; Sökün, Hamza Ümit; Uysal M.; Hasna , Mazen ( IEEE , 2012 , Conference Paper)In this paper, we investigate a multi-carrier multi-relay cooperative system with amplify-and-forward relaying over frequency-selective underwater acoustic channels. Relay selection rules rely on the maximization of ... -
Multi-resampling Doppler compensation in cooperative underwater OFDM systems
Karakaya B.; Hasna , Mazen; Duman T.M.; Uysal M.; Ghrayeb A. ( IEEE , 2013 , Conference Paper)We consider a multi-carrier cooperative underwater acoustic communication (UWAC) system and investigate the Doppler scaling problem arising due to the motion of different nodes. Specifically, we assume an orthogonal frequency ... -
Relay selection for cooperative underwater acoustic communication systems
Karakaya B.; Omar Hasna , Mazen; Uysal M.; Duman T.M.; Ghrayeb A. ( IEEE , 2012 , Conference Paper)In this paper, we consider a multi-carrier and multi-relay underwater acoustic communication (UWAC) system and investigate the relay selection problem. Our channel model is built on an aggregation of both large-scale path ...
