Summary: The underwater channel poses numerous challenges for acoustic communication.Acoustic waves suffer long propagation delay, multipath, fading, and potentiallyhigh spatial and temporal variability. In addition, there is no typical underwateracoustic channel; every body of water exhibits quantifiably different properties. Underwateracoustic modems are traditionally operated at low frequencies. However, theuse of broadband, high frequency communication is a good alternative because of thelower background noise compared to low-frequencies, considerably larger bandwidthand better source transducer efficiency. One of the biggest problems in the underwateracoustic communications at high frequencies is time-selective fading, resultingin the Doppler spread. While many Doppler detection, estimation and compensationtechniques can be found in literature, the applications are limited to systems operatingat low frequencies contained within frequencies ranging from a few hundred Hertzto around 30 kHz.
