Abstract

Impulse noise and large scale single-frequency noise have an enormous effect on underwater acoustic communication and they often exist in the received signal. This paper focuses on noise mitigation when the two kinds of noise both exist. These interferences are sparse, and they have lager amplitudes, which are able to be weakened by using compressed sensing theory reasonably. Based on orthogonal matching pursuit (OMP), this paper uses the observed value to reconstitute the noise and suppressthem. Experimental results performed with numerical simulation and pool-trial data are provided. The results show the improvement of the proposed algorithm under impulse noise mitigation and large scale single-frequency noise mitigation can get more performance gain margin. Through the estimation and suppression of them, the robustness is improved.
