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 ... -
Cooperative BICM-OFDM systems for frequency-selective relay channels
(IEEE, 2011)In this paper, we consider a cooperative multi-carrier multi-relay system over frequency-selective fading channels. Specifically, we adopt the orthogonal frequency division multiplexing (OFDM) with bit-interleaved ... -
Enhanced MRC for decode-and-forward cooperative diversity systems
(IEEE, 2012-10)In this letter, we propose a novel enhanced maximal-ratio combining (E-MRC) scheme for multi-branch decode-and-forward (DF) cooperative diversity systems consisting of a source, a destination, and multiple relays. This ... -
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 ... -
Exact closed-form error probability expression for cooperative diversity networks with channel estimation errors in time selective Rayleigh fading channels
(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 ... -
Fractionally spaced equalization for broadband amplify-and-forward cooperative systems
(IEEE, 2013)In this paper, we revisit the concept of fractionally spaced equalization (FSE) for broadband single-carrier amplify-and-forward (AaF) cooperative systems. Particularly, we investigate fractionally spaced frequency domain ... -
Gamma-gamma türbülans kanallarında tüm-optik rölelemeli FSO sistemleri için röle seçimi
(IEEE, 2014)Bu bildiride, tüm-optiksel çoklu-röle kablosuz optik haberleşme sistemleri için Gamma-Gamma atmosferik türbülans kanalı varsayımı altında servis dışı kalma başarımı incelenmiştir. Röleler arası katı senkronizasyon ihtiyacından ... -
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 ... -
Performance analysis of cooperative diversity networks with imperfect channel estimation
(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
(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 ... -
Performance and optimization of network-coded cooperative diversity systems
(IEEE, 2013-03)In this paper, we study network–coded cooperative diversity (NCCD) systems comprising multiple sources, one relay, and one destination, where the relay detects the packets received from all sources and performs Galois field ... -
Relay selection in dual-hop vehicular networks
(IEEE, 2011-02)In this letter, we investigate cooperative diversity with relay selection over cascaded Rayleigh fading channels. In particular, we analyze the performance of a relay selection scheme for cooperative vehicular networks ...
