Following underwater acoustic channel modeling, this book investigates
the relationship between coherence time and transmission distances. It
considers the power allocation issues of two typical transmission
scenarios, namely short-range transmission and medium-long range
transmission. For the former scenario, an adaptive system is developed
based on instantaneous channel state information. The primary focus is
on cooperative dual-hop orthogonal frequency division multiplexing
(OFDM).This book includes the decomposed fountain codes designed to
enable reliable communications with higher energy efficiency. It covers
the Doppler Effect, which improves packet transmission reliability for
effective low-complexity mirror-mapping-based intercarrier interference
cancellation schemes capable of suppressing the intercarrier
interference power level. Designed for professionals and researchers in
the field of underwater acoustic communications, this book is also
suitable for advanced-level students in electrical engineering or
computer science.
