Multipath-doppler diversity for broadband cooperative vehicular communications
(IEEE, 2011)
Initial works on cooperative vehicular communications build upon the assumption of frequency-flat and quasi-static fading channels. This can be justified only for narrowband systems in very slow traffic flows such as in ...
Moment generating function-based performance evaluation of amplify-andforward relaying in N∗Nakagami fading channels
(IEEE, 2011-02-11)
In this study, the authors investigate the error rate performance of amplify-and-forward relaying over N∗Nakagami fading channels. This is a recently introduced channel model that involves the product of N Nakagami-m-distributed ...
Spectrum trading for non-identical channel allocation in cognitive radio networks
(IEEE, 2011)
In this paper, we investigate spectrum trading via auction approach for cognitive radio networks. We consider a realistic valuation function in terms of different parameters for secondary users (SUs), and propose an efficient ...
Multicarrier HF communications with amplify-and-forward relaying
(IEEE, 2011)
High-frequency (HF) radio communication has been recognized as the primary means for long-range wireless communications since the advent of radio. With its unique features, HF communication continues to be used for a wide ...
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 ...
Performance evaluation of multiple-bit delay detection with majority vote decision rule in optical DPSK systems
(IEEE, 2011)
In this paper, the performance of multiple-bit delay detection (MBDD) systems in optical differential phase shift keying (DPSK) is investigated. Assuming that the dominant noise in the system is originated by the optical ...
Multi-hop relaying over the atmospheric poisson channel
(IEEE, 2011)
In this paper, we study the outage behavior of a decode-and-forward multi-hop free-space optical (FSO) system over a Poisson channel degraded by atmospheric turbulence. We assume that perfect channel side information (CSI) ...
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 ...
Multi-hop coherent free-space optical communications over atmospheric turbulence channels
(IEEE, 2011)
In this paper, we investigate multi-hop relaying as an efficient fading mitigation tool for coherent free-space optical (FSO) systems over atmospheric turbulence channels. We consider an FSO relaying system with ...
Spectrum trading for risky environments in IEEE 802.22 cognitive networks
(IEEE, 2011)
In this paper, we consider the shared used model in the context of IEEE 802.22 cognitive and investigate spectrum trading via auction approach. We consider two different scenarios in which the dominant risk is either ...
