A diversity compression and combining technique based on channel shortening for cooperative networks
Hussain S.I.; Alouini M.-S.; Hasna , Mazen ( IEEE , 2012 , Article)The cooperative relaying process with multiple relays needs proper coordination among the communicating and the relaying nodes. This coordination and the required capabilities may not be available in some wireless systems ... -
A signal combining technique based on channel shortening for cooperative sensor networks
Hussain S.I.; Alouini M.-S.; Hasna , Mazen ( IEEE , 2010 , Conference Paper)The cooperative relaying process needs proper coordination among the communicating and the relaying nodes. This coordination and the required capabilities may not be available in some wireless systems, e.g. wireless sensor ... -
Outage analysis of selective cooperation in underlay cognitive networks with fixed gain relays and primary interference modeling
Hussain S.I.; Alouini M.-S.; Qaraqe K.; Hasna , Mazen ( IEEE , 2012 , Conference Paper)Selective cooperation is a well investigated technique in non-cognitive networks for efficient spectrum utilization and performance improvement. However, it is still a nascent topic for underlay cognitive networks. Recently, ... -
Partial relay selection in underlay cognitive networks with fixed gain relays
Hussain S.I.; Alouini M.-S.; Hasna , Mazen; Qaraqe K. ( IEEE , 2012 , Conference Paper)In a communication system with multiple cooperative relays, selecting the best relay utilizes the available spectrum more efficiently. However, selective relaying poses a different problem in underlay cognitive networks ... -
Performance analysis of best relay selection scheme for amplify-and-forward cooperative networks in identical Nakagami-m channels
Hussain S.I.; Alouini M.-S.; Hasna , Mazen ( IEEE , 2010 , Conference Paper)In cooperative communication networks, the use of multiple relays between the source and the destination was proposed to increase the diversity gain. Since the source and all the relays must transmit on orthogonal channels, ... -
Performance analysis of best relay selection scheme for fixed gain cooperative networks in non-identical Nakagami-m channels
Hussain S.I.; Hasna , Mazen; Alouini M.-S. ( IEEE , 2010 , Conference Paper)Selecting the best relay among all the relays ready to cooperate saves system resources and utilizes the available bandwidth more efficiently compared to the regular all-relay cooperation. This scheme also achieves the ... -
Performance analysis of relay selection schemes in underlay cognitive networks with Decode and Forward relaying
Chamkhia H.; Hasna , Mazen; Hamila R.; Hussain S.I. ( IEEE , 2012 , Conference Paper)In underlay cognitive networks with regenerative relaying, secondary users operating with primary user are adhering to stringent interference constraint which limits their transmission power and coverage area. In order not ... -
Performance analysis of selective cooperation in amplify-and-forward relay networks over identical Nakagami-m channels
Hussain S.I.; Alouini M.-S.; Hasna , Mazen ( Wiley Online Library , 2013 , Article)In cooperative communications, multiple relays between a source and a destination can increase the diversity gain. Because all the nodes must use orthogonal channels, multiple-relay cooperation becomes spectrally inefficient. ... -
Performance analysis of selective cooperation in underlay cognitive networks over Rayleigh channels
Hussain S.I.; Abdallah M.M.; Alouini M.-S.; Hasna , Mazen; Qaraqe K. ( IEEE , 2011 , Conference Paper)Underlay cognitive networks should follow strict interference thresholds to operate in parallel with primary networks. This constraint limits their transmission power and eventually the area of coverage. Therefore, it is ... -
Performance analysis of selective cooperation with fixed gain relays in Nakagami-m channels
Hussain S.I.; Hasna , Mazen; Alouini M.-S. ( elsevier B.V. , 2012 , Article)Selecting the best relay using the maximum signal to noise ratio (SNR) among all the relays ready to cooperate saves system resources and utilizes the available bandwidth more efficiently compared to the regular all-relay ... -
Reactive relay selection in underlay cognitive networks with fixed gain relays
Hussain S.I.; Alouini M.-S.; Qaraqe K.; Hasna , Mazen ( IEEE , 2012 , Conference Paper)Best relay selection is a bandwidth efficient technique for multiple relay environments without compromising the system performance. The problem of relay selection is more challenging in underlay cognitive networks due to ...
