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 ...
Information theoretical performance limits of single-carrier underwater acoustic systems
(IEEE, 2014)
In this study, the authors investigate the information theoretical limits on the performance of point-to-point single-carrier acoustic systems over frequency-selective underwater channels with intersymbol interference. ...
Novel adaptive transmission algorithms for free-space optical links
(IEEE, 2012-12)
Atmospheric turbulence is a major degrading factor in free-space optical (FSO) systems. Since turbulence-induced fading results in a very slowly-varying channel, reliable feedback is possible allowing the implementation ...
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 ...
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 ...
Capacity of hybrid cognitive radio networks with distributed VAAs
(IEEE, 2010-09)
A cooperative hybrid cognitive radio (CR) network is proposed to simultaneously operate on a dedicated licensed band and a secondary band. The licensed band is used for communications between a base station (BS) and mobile ...
Diversity-multiplexing trade-off in coherent free-space optical systems with multiple receivers
(IEEE, 2010-12)
In this paper, from an information theory point of view, we investigate the performance of a coherent freespace optical (FSO) communication system with multiple receive apertures over atmospheric turbulence channels. Our ...
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 ...
Markov-based performance analysis of medium access in visible light communications
(IEEE, 2015)
Visible light communication (VLC) uses the illumination infrastructure to provide high speed wireless connectivity. VLC has recently emerged as a promising alternative/complementary technology to conventional radio-frequency ...
Adaptive unipolar MIMO-OFDM for visible light communications
(IEEE, 2019)
Unipolar orthogonal frequency division multiplexing (U-OFDM) appears as an attractive optical OFDM solution for emerging visible light communication (VLC) systems. This paper proposes spectral efficiency improvement for ...
