Systematic measurements were performed to characterize shallow-water acoustic
propagation channels for applications in the field of underwater communications. The survey …

Traditional channel models for communications research are designed for narrowband
systems. Underwater acoustic communication systems use a bandwidth that is not small …

In past decades there has been a growing interest in discussion and study of using
underwater acoustic channel as the physical layer for communication systems, ranging from …

Underwater acoustic communications are limited by the following channel impairments: time
variability, narrow bandwidth, multipath, frequency selective fading and the Doppler effect …

To further accelerate the practical process of polar codes in underwater acoustic
communication (UWC) and improve the reliability and efficiency of underwater data …

This study investigates the application of artificial fish swarm algorithm (AFSA) in the power
allocation for multiple‐input and multiple‐output orthogonal frequency‐division multiplexing …

Underwater acoustic channel (UAC) is featured as fast time-varying characteristic, and
challenges the transmission designs. To countermine the time variation effect, we propose …

In this paper, we consider a class of single-input-multiple-output (SIMO) underwater acoustic
communication channels, where each propagation path can be characterized by a complex …

In this paper, we present the development of a multicarrier modulation system of low
complexity for broadband underwater acoustic communications (UAC), whose frequency …

Underwater acoustic channels are among the most challenging communication media. Time-
varying multipath fading, long delay spread, significant Doppler spread, and frequency …
