Channel estimation in underwater cooperative OFDM system with amplify-and-forward relaying
(IEEE, 2012)
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 resence of sparse underwater acoustic ...
Outage performance and diversity gain analysis of free-space optical multi-hop parallel relaying
(IEEE, 2013-08)
In this paper, we investigate the outage performance of free-space optical mesh networks, which build upon the combination of serial (multi-hop) and parallel relaying. We assume log-normal atmospheric turbulence channels ...
High-rate distributed space-time-frequency coding for wireless cooperative networks
(IEEE, 2011-02)
In this paper, we propose high-rate distributed space-time-frequency codes (DSTFCs) to exploit maximum achievable diversity gains over frequency-selective fading channels. The proposed designs achieve full-rate for any ...
Achievable data rates and power allocation for frequency-selective fading relay channels with imperfect channel estimation
(Springer Science+Business Media, 2012-12)
In this article, we investigate the information-theoretical performance of a cooperative orthogonal frequency division multiplexing (OFDM) system with imperfect channel estimation. Assuming the deployment of training-aided ...
Handover in VLC networks with coordinated multipoint transmission
(IEEE, 2018-01-31)
In this work, we consider a cellular visible light communication (VLC) network where each ceiling luminary serves as an access point (AP). The network is assumed to support coordinated multipoint transmission (CoMP). The ...
Performance of coherent differential phase-shift keying free-space optical communication systems in M-distributed turbulence
(IEEE, 2013-07)
In this paper, we investigate the error rate performance of a coherent free-space optical communication system with differential phase-shift keying over M-distributed turbulence channels. In our derivations, we express the ...
Cooperative communication techniques for future-generation HF radios
(IEEE, 2012-10)
When Hurricane Katrina hit the Gulf Coast of the United States in 2005, it severely damaged the telecommunications infrastructure, isolating the area from the outside world. With all the high-end emergency communication ...
A novel pulse-positioned coding scheme for fiber fault monitoring of a PON
(IEEE, 2011-09)
In this letter, we propose a novel optical coding scheme for fiber link quality monitoring of a passive optical network (PON). The proposed scheme named incrementally pulse positioned coding (IPPC) is practically very ...
UAV-based FSO communications for high speed train backhauling
(IEEE, 2019)
In line with the increasing number of high speed train (HST) commuters and their demand for mobile data, railways operators expore means of providing high speed on-board wireless access. The data from all train cars are ...
Statistical modeling of propagation channels for Terahertz band
(IEEE, 2017)
Digital revolution and recent advances in telecommunications technology enable to design communication systems which operate within the regions close to the theoretical capacity limits. Ever-increasing demand for wireless ...
