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 ...
A novel statistical model for turbulence-induced fading in free-space optical systems
(IEEE, 2013)
In this paper, we propose a new probability distribution function which accurately describes turbulence-induced fading under a wide range of turbulence conditions. The proposed model, termed Double GG distribution, is based ...
Outage performance and diversity gain analysis of free-space optical multi-hop parallel relaying
(IEEE, 2013-08)
In this paper, we investigate the outage performance of free-space optical mesh networks, which build upon the combination of serial (multi-hop) and parallel relaying. We assume log-normal atmospheric turbulence channels ...
İşbirlikli haberleşmede birleştirilmiş zaman kayması ve sönümlemeli kanal katsayısı kestirimi
(IEEE, 2013)
In this paper, we investigate joint channel gain and time offset estimation for two different data aided methods in cooperative communication with amplify-and-forward (AF) relaying. First one is the Cascaded Estimation ...
Cooperative transmission for broadband vehicular networks over doubly selective fading channels
(IEEE, 2012-06)
Cooperative communication has been recently applied to vehicular networks to enable coverage extension and enhance link reliability through distributed spatial diversity. In this study, the authors investigate the performance ...
Optimal relay placement and diversity analysis of relay-assisted free-space optical communication systems
(IEEE, 2013-01)
Relay-assisted free-space optical (FSO) transmission exploits the fact that atmospheric turbulence fading variance is distance dependent and yields significant performance gains by taking advantage of the resulting shorter ...
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 ...
Optimal combiners in optical wireless systems with spatial diversity and pre-amplification
(IEEE, 2016)
We present analytical results on the operation of a pre-amplified optical wireless communication (OWC) system that also takes advantage of spatial diversity to improve its outage probability and average bit-error-rate (BER) ...
A novel statistical channel model for turbulence-induced fading in free-space optical systems
(IEEE, 2015-06-01)
In this paper, we propose a new probability distribution function which accurately describes turbulence-induced fading under a wide range of turbulence conditions. The proposed model, termed double-generalized gamma (double ...
Network-coded cooperative systems with generalized user-relay selection
(IEEE, 2020-11)
We consider a network-coded cooperative (NCC) system that consists of N >= 2 sources, M >= 1 decodeand-forward (DF) relays, and a single destination. The relays perform network coding (NC) on the received sources' symbols ...
