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 ...
Görünür ışık kanalların modellenmesi ve ACO-OFDM için başarım analizi
(IEEE, 2015)
Spectrum scarcity of traditional radio communication has led communication engineers to find new alternatives. Indoor visible light communication is one alternative to solve this problem since its spectrum is not regulated ...
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 ...
Analysis of field correlations in atmospheric optical MIMO systems
(IEEE, 2014)
In this paper, we evaluate the absolute field correlations for a free space optical (FSO) multiple-input multiple-output (MIMO) link operating in a turbulent atmosphere. Such knowledge is needed in heterodyne reception to ...
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 ...
Asymptotic performance of generalized transmit laser selection over lognormal turbulence channels
(IEEE, 2020-08)
In free space optical communication systems, transmit laser selection (TLS) has been proposed as an efficient fading-mitigation technique over turbulence channels. In TLS, the transmitter is equipped with a number of laser ...
