Generalized maximum-likelihood sequence detection for photon-counting free space optical systems
(IEEE, 2010-12)
We investigate detection methods for on-off keying (OOK) photon-counting Free Space Optical (FSO) systems in the presence of turbulence-induced fading, assuming no channel state information at the receiver. To recover the ...
Spectrum sensing of correlated subbands with colored noise in cognitive radios
(IEEE, 2012)
In this paper, we consider the problem of wideband spectrum sensing by using the correlation among the observation samples in different subbands. The Primary User (PU) signal samples in occupied subbands are assumed to be ...
Visible light channel modeling for gas pipelines
(IEEE, 2018-04)
In this paper, we explore the use of visible light communication as a means of wireless monitoring in gas pipelines. In an effort to shed light on the communication limits in the presence of gas, we create a three-dimensional ...
Centralized light access network (C-LiAN): a novel paradigm for next generation indoor VLC networks
(IEEE, 2017)
Visible light communication (VLC) builds upon the idea of using existing lighting infrastructure for wireless data transmission. In a conventional VLC network, each light fixture acts as an access point (AP) which are ...
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) ...
eU-OFDM based multiple access for visible light communication networks
(IEEE, 2017)
In this paper, we propose a novel protocol for cooperative multiple access in visible light communication (VLC) networks. The proposed protocol exploits the features of enhanced unipolar orthogonal frequency division ...
Performance and optimization of network-coded cooperative diversity systems
(IEEE, 2013-03)
In this paper, we study network–coded cooperative diversity (NCCD) systems comprising multiple sources, one relay, and one destination, where the relay detects the packets received from all sources and performs Galois field ...
Sparse channel estimation for OFDM-based underwater cooperative systems with amplify-and-forward relaying
(IEEE, 2014)
This paper is concerned with a challenging problem of channel estimation for amplify-and-forward cooperative relay based orthogonal frequency division multiplexing (OFDM) systems in the presence of sparse underwater acoustic ...
Spectrum trading for risky environments in IEEE 802.22 cognitive networks
(IEEE, 2011)
In this paper, we consider the shared used model in the context of IEEE 802.22 cognitive and investigate spectrum trading via auction approach. We consider two different scenarios in which the dominant risk is either ...
Multi-resampling doppler compensation in cooperative underwater OFDM systems
(IEEE, 2013)
We consider a multi-carrier cooperative underwater acoustic communication (UWAC) system and investigate the Doppler scaling problem arising due to the motion of different nodes. Specifically, we assume an orthogonal frequency ...
