In past years there has been a growing interest in the study of underwater acoustic channel as the physical layer for communication systems, ranging from point-to-point communications to underwater multicarrier modulation networks. Recently, compressed sensing (CS) has achieved a fast-growing interest by exploiting the sparse nature of UWA channels in OFDM communication networks. This paper studies selected characterizations of the UWA channels, and reviews several mathematical UWA channel models in the literature. We try to provide an overview of the key developments, both theoretical and applied, in the particular topics regarding multicarrier communication for underwater acoustic communication such as the channel and Doppler shift estimation.

Keywords- Underwater Communication; Multicarrier Communication, Compressed/compressive sensing, ,time-varying systems, orthogonal frequency division multiplexing, pilot-based sparse channel estimation
