Diversity-multiplexing trade-off in coherent free-space optical systems with multiple receivers
Aghajanzadeh, S. M.; Uysal, Murat (IEEE, 2010-12)In this paper, from an information theory point of view, we investigate the performance of a coherent freespace optical (FSO) communication system with multiple receive apertures over atmospheric turbulence channels. Our ... -
DMT analysis of coherent free-space optical systems over atmospheric turbulence channels
Aghajanzadeh, S. M.; Uysal, Murat (IEEE, 2010)In this paper, we investigate the diversity-multiplexing tradeoff (DMT) performance of a coherent free-space optical (FSO) communication system with multiple receive apertures over atmospheric turbulence channels. Our study ... -
DMT analysis of multi-hop coherent FSO communication over atmospheric channels
Aghajanzadeh, S. M.; Uysal, Murat (IEEE, 2011)In this paper, we investigate the diversity-multiplexing tradeoff (DMT) of a multi-hop coherent free-space optical (FSO) system over atmospheric channels. We consider a relay-assisted FSO system with decode-and-forward ... -
Information theoretic analysis of hybrid-ARQ protocols in coherent free-space optical systems
Aghajanzadeh, S. M.; Uysal, Murat (IEEE, 2012-05)Automatic retransmission request (ARQ) is a feedback-based data link layer technique which enhances the reliability of communication in fading channels. In this paper, we investigate the performance of hybrid-ARQ (H-ARQ) ... -
Multi-hop coherent free-space optical communications over atmospheric turbulence channels
Aghajanzadeh, S. M.; Uysal, Murat (IEEE, 2011)In this paper, we investigate multi-hop relaying as an efficient fading mitigation tool for coherent free-space optical (FSO) systems over atmospheric turbulence channels. We consider an FSO relaying system with ... -
Outage analysis of Hybrid-ARQ protocols in coherent free-space optical communications
Aghajanzadeh, S. M.; Uysal, Murat (IEEE, 2011)In this paper, we investigate the performance of automatic retransmission request (ARQ) protocols in coherent free-space optical (FSO) communications. Specifically, we study the outage performance of three different ... -
Outage performance and DMT analysis of DF parallel relaying in FSO IM/DD communications
Aghajanzadeh, S. M.; Uysal, Murat (IEEE, 2012)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 ... -
Performance analysis of parallel relaying in free-space optical systems
Aghajanzadeh, S. M.; Uysal, Murat (IEEE, 2015-11)In this paper, we investigate the information theoretic performance of parallel relaying in free-space optical (FSO) communications over Gamma-Gamma fading channels. We consider an intensity modulation/direct-detection ...
