Channel estimation for amplify-and forward relaying: cascaded against disintegrated estimators
(IEEE, 2010)
The authors investigate the performance of amplify-and-forward relaying with two different pilot-symbol-assisted channel estimation methods. In the first estimation method, the cascaded channel consisting of source-to-relay ...
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 ...
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 ...
Pilot-aided channel estimation on SC-PAM based visible light communications
(IEEE, 2018-07-02)
Estimation of the time-varying optical wireless channel response is crucial in order to decode received signals coherently. In this work, we investigate symbol-error-rate and mean absolute error performance of different ...
İşbirlikli haberleşmede birleştirilmiş zaman kayması ve sönümlemeli kanal katsayısı kestirimi
(IEEE, 2013)
In this paper, we investigate joint channel gain and time offset estimation for two different data aided methods in cooperative communication with amplify-and-forward (AF) relaying. First one is the Cascaded Estimation ...
EM-based joint time delay and channel estimation for cooperative communications
(IEEE, 2011)
In this paper, we study joint time delay and channel estimation for a cooperative communication system with amplify-and-forward (AF) relaying. The proposed joint estimator is based on Expectation-Maximization (EM) algorithm ...
Error probability of DF relaying with pilot-assisted channel estimation over time-varying fading channels
(IEEE, 2012-01)
In this paper, we investigate the error rate performance of a cooperative network with adaptive decode-and-forward (DF) relaying over time-selective frequency-flat Rayleigh-fading channels. We assume pilot-symbol-assisted ...
On the performance analysis of multirelay cooperative diversity systems with channel estimation errors
(IEEE, 2011-06)
In this paper, we investigate the performance of an amplify-and-forward (AF) cooperative diversity system with multiple relays in the presence of channel estimation errors. We consider both conventional relaying (in which ...
Finite-SNR DMT analysis for multisource multirelay NCC systems with imperfect CSI
(IEEE, 2016)
Network coded cooperative (NCC) systems have recently attracted attention with their high spectral and power efficiency. In this paper, we investigate the information theoretical limits of NCC systems in the presence of ...
Renkli̇ Gauss gürültülü seyrek sualtı akusti̇k kanalların kesti̇ri̇mi̇
(IEEE, 2012)
İşbirlikli sualtı kablosuz iletişim sistemleri konusu son yıllarda büyük önem kazanmıştır. Özellikle sualtı akustik kanalların seyrek (sparse) olma özelliği taşıması ve sisteme giren toplamsal gürültünün renkli Gauss ...
