Impact of inter-channel interference on shallow underwater acoustic OFDM systems

This paper investigates the impacts of InterChannel Interference (ICI) effects on a shallow underwater acoustic (UWA) orthogonal frequency-division multiplexing (OFDM) communication system. Considering both the turbulence of the water surface and the roughness of the bottom, a stochastic geometry-based channel model utilized for a wideband transmission scenario has been exploited to derive a simulation model. Since the system bandwidth and the subcarrier spacing is very limited in the range of a few kHz, the channel capacity of a UWA system is severely suffered by the ICI effect.
