• Reed-Solomon coding for cooperative wireless communication 

      Shakeel I.; Hasna , Mazen; Abu-Dayya A.; Ghrayeb A. ( IEEE , 2010 , Conference Paper)
      During the last few years, several authors have studied the performance of many different types of channel codes for cooperative communication systems. Some of these codes include Low Density Parity Check (LDPC), Turbo and ...
    • Relay assignment in multiple source-destination cooperative networks with limited feedback 

      Zhang, X.; Jafarkhani, H.; Ghrayeb, A.; Hasna, M.O. ( Institute of Electrical and Electronics Engineers Inc. , 2014 , Article)
      We consider in this paper relay assignment for cooperative systems with mutiple source-destination pairs. The objective here is to assign relays to the source-destination pairs in such a way that all pairs achieve the ...
    • Relay assignment in network-coded cooperative systems with M-PSK modulation over asymmetric channels 

      Zhang X.; Ghrayeb A.; Hasna , Mazen ( IEEE , 2010 , Conference Paper)
      We consider in this paper relay assignment for cooperative systems with multiple two-way relay channels. The nodes corresponding to one two-way relay channel (henceforth referred to as pair) communicate with each other ...
    • 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 ...
    • Self-Energized UAV-Assisted scheme for cooperative wireless relay networks 

      Jayakody D.N.K.; Perera T.D.P.; Ghrayeb A.; Hasna , Mazen ( Institute of Electrical and Electronics Engineers Inc. , 2020 , Article)
      Unmanned aerial vehicles (UAVs) have recently been envisaged as an enabling technology of 5G. UAVs act as an intermediate relay node to facilitate uninterrupted, high quality communication between information sources and ...
    • Threshold-based relaying in coded cooperative networks 

      Al-Habian G.; Ghrayeb A.; Hasna , Mazen; Abu-Dayya A. ( IEEE , 2011 , Article)
      In cooperative communications, error propagation at the relay nodes degrades the diversity order of the system. To combat that effect, we present a novel technique to control error propagation at the relays, which is ...
