Adaptive Modulation for Long-Range Underwater Acoustic Communication
IEEE Transactions on Wireless Communications, 2020Long-range underwater acoustic communication (LR-UWAC) refers to the peer-to-peer transmission of messages for distances of tens to hundreds of km. It is a key enabling technique for applications such as control over unmanned underwater vehicles for long-

Real Signal DHT-OFDM With Index Modulation for Underwater Acoustic Communication
IEEE Journal of Oceanic Engineering, 2023This article presents orthogonal frequency division multiplexing (OFDM) that is based on discrete Hartley transform (DHT) as a modulation transform for underwater acoustic (UWA) communication instead of the conventional discrete Fourier transform (DFT ...

Synchronization techniques for underwater acoustic communications
International Journal of Communication Systems, 2023SummaryUnderwater acoustic channel is a challenging medium for communication due to the presence of significant multipath, high noise, frequency‐dependent propagation loss, and high and non‐uniform Doppler spread. Doppler shift is non‐negligible in underwater communication due to the low velocity of underwater signals.
