Multi-resampling Doppler compensation in cooperative underwater OFDM systems
(
IEEE
, 2013 , Conference Paper)
We consider a multi-carrier cooperative underwater acoustic communication (UWAC) system and investigate the Doppler scaling problem arising due to the motion of different nodes. Specifically, we assume an orthogonal frequency ...
Inter-relay Interference management schemes for multi-user cooperative wireless networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
In this paper, two cooperative communications schemes with inter-relay interference (IRI) management are proposed for multi-user wireless networks. The first scheme (Interference management at relay station (IMR)) uses the ...
Area spectral efficiency of cooperative network with DF and AF relaying
(
IEEE
, 2012 , Conference Paper)
Most performance metrics for cooperative networks focus on the qualification of either spectrum efficiency or link reliability, without considering the spatial effect of radio transmission. Area spectral efficiency (ASE) ...
Cooperative OFDM systems for UWAC with SNR-based relay selection schemes
(
IEEE
, 2012 , Conference Paper)
In this paper, we investigate a multi-carrier multi-relay cooperative system with amplify-and-forward relaying over frequency-selective underwater acoustic channels. Relay selection rules rely on the maximization of ...
