A simulation study of cooperative underwater acoustic communication
Cooperative communication promises significant performance gains in terms of link reliability, spectral efficiency, system capacity, and transmission range. Due to its indisputable advantages for high-speed underwater ...
Optimal relay placement in cooperative free-space optical communication systems
Relay-assisted free-space optical (FSO) transmission exploits the fact that atmospheric turbulence fading variance is distance dependent and yields significant performance gains by taking advantage of the resulting shorter ...
Cooperative transmission for broadband vehicular networks over doubly selective fading channels
Cooperative communication has been recently applied to vehicular networks to enable coverage extension and enhance link reliability through distributed spatial diversity. In this study, the authors investigate the performance ...
Sualtı akustik haberleşmesi için SNR tabanlı röle seçimi kullanan işbirlikli OFDM sistemleri
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 ...
Relay selection for cooperative underwater acoustic communication systems
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 ...
Outage capacity regions of multicarrier DF relaying in underwater acoustic channels
In this paper, we investigate the information theoretical limits on the performance of cooperative multicarrier underwater acoustic (UWA) communication systems. We assume decode-and-forward (DF) relaying and consider ...
Outage performance and DMT analysis of DF parallel relaying in FSO IM/DD communications
In this paper, we investigate the performance of cooperative diversity transmission in free-space optical (FSO) communications. We consider an FSO cooperative diversity system with a single decode-and-forward relay and a ...
Cooperative communication techniques for future-generation HF radios
When Hurricane Katrina hit the Gulf Coast of the United States in 2005, it severely damaged the telecommunications infrastructure, isolating the area from the outside world. With all the high-end emergency communication ...
