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

The purpose of this work is to present a flexible system that supports the study of wideband
underwater acoustic communications (UAC). It has been developed both to measure …

For orthogonal frequency division multiplexing (OFDM) systems in high-mobility scenarios,
the estimation of time-varying multipath channels not only has a large error, which affects …

Communication with the underwater vehicles during their tasks is one of the most important
issues. The need for real-time data transfer raises the necessity of developing …

We propose a novel multi-agent approach for auto-adjusting OFDM parameters for
underwater acoustic communication that utilizes distributed optimization to perform a …

Underwater acoustic (UWA) communication holds immense potential for military
applications due to the unique challenges posed by the underwater environment. While …
