Underwater acoustic (UWA) wireless communication has recently attracted attention for many applications including oceanographic data collection, pollution monitoring, seismic activities measurement, exploration of natural resources among others. Orthogonal frequency division multiplexing (OFDM) combined with multi-relay cooperative transmission provides additional spatial diversity compared to conventional non-cooperative UWA systems. I am analyzing the Intercarrier interference (ICI) due to non-uniform Doppler distortion, proposing different receiver structures, and deriving expressions for ICI matrices. I am also investigating the outage performance for a cooperative OFDM UWA communication system, both amplify-and-forward (AF) and decode-and-forward (DF) relaying schemes. I am deriving analytical expressions as bounds on outage probability and outage capacity. Monte-Carlo simulations corroborate the enhanced performance of cooperative OFDM UWA communication systems. I am analyzing the effects of relay location and carrier frequency on outage probability for both relaying schemes.
