Adaptive bit loading for multi-relay cooperative orthogonal frequency division multiple with imperfect channel estimation
Amin, O.; Ikki, S. S.; Uysal, Murat (IEEE, 2012-08-14)In this study, the authors introduce an adaptive bit loading scheme for an amplify-and-forward orthogonal frequency division multiple cooperative system with relay selection. The proposed bit loading scheme maximises the ... -
Adaptive power loading for multi-relay OFDM regenerative networks with relay selection
Amin, O.; Uysal, Murat (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 ... -
Channel estimation for amplify-and forward relaying: cascaded against disintegrated estimators
Amin, O.; Gedik, B.; Uysal, Murat (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 ... -
On the performance analysis of multirelay cooperative diversity systems with channel estimation errors
Amin, O.; Ikki, S. S.; Uysal, Murat (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 ... -
Optimal bit and power loading for amplify-and-forward cooperative OFDM systems
Amin, O.; Uysal, Murat (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 ... -
Performance analysis of cooperative diversity networks with imperfect channel estimation
Ikki, S. S.; Amin, O.; Uysal, Murat (IEEE, 2010)In this paper, we investigate the effect of channel estimation error on the error rate performance of a multi-relay system with amplify-and-forward relaying. We consider orthogonal relaying and study both conventional ...
