The underwater channel poses numerous challenges for acoustic communication.
Acoustic waves suffer long propagation delay, multipath, fading, and potentially
high spatial and temporal variability. In addition, there is no typical underwater
acoustic channel; every body of water exhibits quantifiably different properties. Underwater
acoustic modems are traditionally operated at low frequencies. However, the
use of broadband, high frequency communication is a good alternative because of the
lower background noise compared to low-frequencies, considerably larger bandwidth
and better source transducer efficiency. One of the biggest problems in the underwater
acoustic communications at high frequencies is time-selective fading, resulting
in the Doppler spread. While many Doppler detection, estimation and compensation
techniques can be found in literature, the applications are limited to systems operating
at low frequencies contained within frequencies ranging from a few hundred Hertz
to around 30 kHz. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2015. / FAU Electronic Theses and Dissertations Collection
