Outage analysis of Hybrid-ARQ protocols in coherent free-space optical communications
(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 capacity and throughput analysis of multiuser FSO systems
(IEEE, 2015)
In this paper, we investigate the performance of free space optical (FSO) systems with a multiuser scheme employing select-max scheduling technique. Specifically, we consider an FSO communication system which employs a ...
Sparse channel estimation and equalization for OFDM-based underwater cooperative systems with amplify-and-forward relaying
(IEEE, 2016-01-01)
This paper is concerned with a challenging problem of channel estimation and equalization for amplifyand- forward cooperative relay based orthogonal frequency division multiplexing (OFDM) systems in sparse underwater ...
Aperture averaging in multiple-input single-output free-space optical systems
(SPIE, 2015-06)
Multiple-input single-output systems are employed in free-space optical links to mitigate the degrading effects of atmospheric turbulence. We formulate the power scintillation as a function of transmitter and receiver ...
Emerging optical wireless communications-advances and challenges
(IEEE, 2015-09)
New data services and applications are emerging continuously and enhancing the mobile broadband experience. The ability to cope with these varied and sophisticated services and applications will be a key success factor for ...
Ultraviolet communications for ground-to-air links
(IEEE, 2019)
Ultraviolet (UV) communication enables non-line-of-sight (NLOS) wireless connectivity through strong molecular and aerosol scattering. Due to their NLOS nature, UV links bring robustness to blockage or shadowing and relax ...
DMT analysis of coherent free-space optical systems over atmospheric turbulence channels
(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 ...
Visible light communications: from theory to industrial standardization
(IEEE, 2019)
Visible light communication (VLC) builds upon the ubiquitous presence of LEDs and exploits the existing illumination infrastructure for wireless access. VLC provides high data rate transmission in unregulated optical ...
Sparse channel estimation for OFDM-based underwater acoustic systems in rician fading with a new OMP-MAP algorithm
(IEEE, 2019-03-15)
In this paper, a new channel estimation algorithm is proposed that exploits channel sparsity in the time domain for an orthogonal frequency division multiplexing (OFDM)-based underwater acoustical (UWA) communications ...
Enhanced MRC for decode-and-forward cooperative diversity systems
(IEEE, 2012-10)
In this letter, we propose a novel enhanced maximal-ratio combining (E-MRC) scheme for multi-branch decode-and-forward (DF) cooperative diversity systems consisting of a source, a destination, and multiple relays. This ...
