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 ...
Information theoretic analysis and optimization of underwater acoustic communication systems
(IEEE, 2013)
In this paper, we investigate the information theoretical limits of underwater acoustic channel with intersymbol interference. Under the assumptions of sparse and frequency-selective Rician fading channel and non-white ...
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 ...
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 ...
Cooperative underwater acoustic communications
(IEEE, 2013-07)
This article presents a contemporary overview of underwater acoustic communication (UWAC) and investigates physical layer aspects on cooperative transmission techniques for future UWAC systems. Taking advantage of the ...
Capacity analysis of free space optical links for a partially coherent gaussian beam over a turbulent channel with pointing errors
(IEEE, 2013)
In this paper, we investigate the joint effects of
beam width and the spatial coherence length in a partially coherent free-space optical (FSO) link from the information theory perspective, taking into account the combined ...
Spectrum trading for non-identical channel allocation in cognitive radio networks
(IEEE, 2013)
In this paper, we investigate spectrum trading via auction approach for exclusive usage spectrum access model in cognitive radio networks. We consider a realistic valuation function which depends on channel capacity, delay ...
Sualtı işbirlikli OFDM sistemleri için MP-SAGE kanal kestirimi
(2013)
In this paper, an efficient channel estimation algorithm is proposed for amplify-and-forward (AF) cooperative relay based orthogonal frequency division multiplexing (OFDM) system in the presence of sparse underwater acoustic ...
