Abstract

Underwater acoustic communication has multipath error because of reflection by sea-level and sea-bottom. The multipath of UWA channel causes signal distortion and error floor. In this paper, we proposed the compensation method of multipath effect using the impulse response of the UWA channel. As shown in simulation results, the performance of proposed compensation method is better than the performance of conventional method.
