Optimal bit and power loading for amplify-and-forward cooperative OFDM systems
(IEEE, 2011-03)
In this paper, we investigate bit and power allocation strategies for an orthogonal frequency division multiplexing (OFDM) cooperative network over frequency-selective fading channels. We assume amplify-and-forward relaying ...
Single color networks: OFDM-based visible light broadcasting
(IEEE, 2015)
In this study, we investigate the performance of optical orthogonal frequency division multiplexing (O-OFDM) based visible light broadcasting. Although indoor spaces usually have more than one light source, most of the ...
Performance of OFDM-based adaptive visible light communications
(IEEE, 2017)
In this paper, we investigate the performance of a direct current biased optical orthogonal frequency division multiplexing (DCO-OFDM) based adaptive transmission in the context of visible light communication (VLC). We ...
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 ...
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 ...
Relay-assisted OFDM-based visible light communications over multipath channels
(IEEE, 2015-07)
In this paper, we investigate the performance of relay-assisted visible light communication (VLC) system over multipath channels. We consider an indoor environment where the ceiling light serves as the information source ...
Adaptive power loading for multi-relay OFDM regenerative networks with relay selection
(IEEE, 2012-03)
In this paper, we propose an adaptive power loading algorithm for an OFDM (orthogonal frequency division multiplexing)-based multi-relay regenerative network with relay selection. The proposed scheme is based on selecting ...
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 ...
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 ...
Link adaptation for MIMO OFDM visible light communication systems
(IEEE, 2017-11-10)
In this paper, we investigate link adaptation for an orthogonal frequency division multiplexing (OFDM)-based multiple-input multiple-output (MIMO) visible light communication (VLC) system. The proposed adaptive OFDM VLC ...
