Specifically, we assume an orthogonal frequency division multiplexing (OFDM) system with amplify and forward (AF) relaying. Our channel model is built on large-scale path loss along with the short-term frequency-selective fading. For Doppler scaling compensation, we use multi-resampling (MR) receiver designs both at the relay and destination nodes. We present an extensive Monte Carlo simulation study to evaluate the error rate performance of the proposed UWAC system. In simulations, we use the publicly available VirTEX software in conjunction with the ray-tracing based BELLHOP software to precisely reflect the characteristics of an underwater geographical location and the movement of the nodes. © 2013 IEEE.Englishamplify and forward relayingDoppler scalingUnderwater acoustic communicationsAmplify-and-forward relayingDopplerError rate performanceGeographical locationsMonte- carlo simulationsOrthogonal frequency division multiplexing systemsUnderwater acoustic communication (UWAC)Underwater acoustic communicationsCommunication channels (information theory)Monte Carlo methodsOrthogonal frequency division multiplexingSpace-time block coding (STBC)Telecommunication systemsUnderwater acousticsCooperative communicationConference Paper10.1109/OCEANS-Bergen.2013.6608114
