Information Theoretical Performance Analysis and Optimisation of Cooperative Underwater Acoustic Communication Systems
Abstract
In this study the authors investigate the information theoretical limits on the performance of single-carrier cooperative underwater acoustic communication systems in the presence of intersymbol interference. The authors assume decode-and-forward relaying and consider orthogonal half-duplex cooperation. Under the assumptions of sparse and frequency-selective Rician fading channel and non-white correlated Gaussian ambient noise the authors derive expressions for bounds on the individual and achievable rates for both cases where channel state information is available at the transmitter or not. Using these expressions the authors optimise input signalling and relay location to maximise average achievable rates.

Outage probability of a cooperative maximum ratio transmission [İşbirlikli maksimum oranlı iletimin kesinti olasılığı]
Authors:Erdoǧan, Eylem; Muşta, Mahmut Sami; Güçlüoǧlu, Tansal
Publisher and Date:(IEEE Computer Society, 2014)In this paper we present a cooperative communication system employing maximum ratio transmission technique and its outage probability performance over Rayleigh fading channels. Since maximum ratio transmission can achieve full diversity when used at tranmitters having multiple antennas while requiring no complexity increase at the receiver the proposed system can be a preferable structure to be used both at the source and amplify-forward type relays of wireless networks to provide high speed and ...

New channel estimation techniques for cooperative underwater acoustic OFDM systems
Authors:Mustafa, Erdoğan
Publisher and Date:Cooperative underwater acoustic communication systems come into prominence in recent years. Since underwater channels are sparse and additive noise entering the system is colored Gaussian noise it is very difficult to estimate the underwater channels and theoretically makes it interesting. in the first part of the thesis the transmission from source to the target recipient is realized by means of a relay system. Orthogonal frequency division multiplexing (OFDM)-based channel estimation problem is ...
