An adaptive modulation scheme for coded free-space optical systems
(IEEE, 2014)For very slowly-varying fading channels as in the case of atmospheric turbulence-induced fading, it is possible to reliably estimate the channel state information and send it back to the transmitter. The transmitter can ... -
End-to-end performance of mixed RF/FSO transmission systems
(IEEE, 2013-11)In this paper, we consider a heterogenous scenario where free-space optical (FSO) and radio-frequency (RF) technologies are deployed together as a dual-hop communication system, and we investigate the end-to-end outage ... -
Information theoretic analysis of hybrid-ARQ protocols in coherent free-space optical systems
(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) ... -
Novel adaptive transmission algorithms for free-space optical links
(IEEE, 2012-12)Atmospheric turbulence is a major degrading factor in free-space optical (FSO) systems. Since turbulence-induced fading results in a very slowly-varying channel, reliable feedback is possible allowing the implementation ... -
Performance analysis of parallel relaying in free-space optical systems
(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 ...
