Abstract

This paper proposes estimation of underwater acoustic channel in the delay-Doppler domain under dynamic sea conditions. The sparsity of the channel in the delay-Doppler domain is exploited via advanced compressive sensing (CS) technique to estimate the channel. The proposed use of CS with prior information takes care of relatively dominant but stable slowly time-varying channel component and the rapidly fluctuating high energy transients. Simulation results are presented on prior estimated channel of SPACE08 experiment, considered as ground truth, for the validation of the theory presented.
