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 ... -
Error probability of DF relaying with pilot-assisted channel estimation over time-varying fading channels
Ikki, S. S.; Al-Dharrab, S.; Uysal, Murat (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 ... -
Exact closed-form error probability expression for cooperative diversity networks with channel estimation errors in time selective Rayleigh fading channels
Ikki, S. S.; Al-Dharrab, S. I.; Uysal, Murat (IEEE, 2010)In this paper, we investigate the performance of a cooperative network with adaptive decode-and-forward (DF) relaying over time-selective frequency-flat Rayleigh fading channels. In adaptive DF relaying, only a subset of ... -
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 ... -
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 ... -
Performance analysis of cooperative diversity networks with imperfect channel estimation over Rician fading channels
Ikki, S. S.; Feteiha, M.; Uysal, Murat (IEEE, 2010)In this paper, we examine the effect of channel estimation error on the error and outage probabilities of a multi-relay system with amplify-and-forward relaying over frequency-flat Rician fading channel. We consider ...
