    Frequency Domain Based Approach for Denoising of Underwater Acoustic Signal Using EMD.Mathews M. Philip, Rajendran Velayutham & Vijayabaskar Veeraiyan - 2013 - Journal of Intelligent Systems 22 (1):67-80.
    . Underwater communication is usually affected by ambient noise, which may be generated by different sources, such as the wind origin sea-surface sources, ships and under water life. The properties of background noise, which are non-stationary in nature, depend on location, sea depth, wind speed and sound propagation conditions in the area. Overall performance of underwater acoustic instruments can be improved by denoising the underwater signals. This paper proposes a novel denoising method using empirical mode decomposition technique. Frequency domain based (...)
