Modulating retroreflector based free space optical link for UAV-to-ground communications
Dabiri, M. T.; Rezaee, M.; Mohammadi, L.; Javaherian, F.; Yazdanian, V.; Hasna, M. O.; Uysal, Murat (IEEE, 2022-10)Weight reduction and low power consumption are key requirements in the next generation of unmanned aerial vehicle (UAV) networks. Employing modulating retro-reflector (MRR)-based free space optical (FSO) technology is an ... -
Multi-resampling doppler compensation in cooperative underwater OFDM systems
Karakaya, B.; Hasna, M. O.; Duman, T. M.; Uysal, Murat; Ghrayeb, A. (IEEE, 2013)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.; Hasna, M. O.; Uysal, Murat; Duman, T. M.; Ghrayeb, A. (IEEE, 2012)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 ... -
Sualtı akustik haberleşmesi için SNR tabanlı röle seçimi kullanan işbirlikli OFDM sistemleri
Karakaya, B.; Sökün, Hamza Ümit; Uysal, Murat; Hasna, M. O. (IEEE, 2012)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 ...
