In the past decades, researchers/scientists have paid attention to the physical layer of
underwater communications (UWCs) due to a variety of scientific, military, and civil tasks …

This paper presents and experimentally demonstrates energy and spectral efficient index
modulation (IM) scheme for underwater wireless optical communications (UWOC). The …

The world population is rapidly increasing, which in turn increases food needs. On the other
hand, food production is the main cause of water withdrawal. Precision agriculture, based on …

To cope with the extremely double-dispersive channels in underwater acoustic (UWA)
communication, orthogonal time frequency space (OTFS) modulation has been regarded as …

The strong multipath and long delay extensions can lead to large errors in the timing offset
estimation and carrier frequency offset estimation of the Orthogonal Frequency Division …

In a multiple-sequences-spread-spectrum (MSSS) communication system, the transmitted
signal is made up of superimposed cyclic shift sequences, each sequence carrying a …

Employing a cyclic prefixed OFDM (CP-OFDM) communication waveform for sensing has
attracted extensive attention in vehicular integrated sensing and communications (ISAC). A …

Nowadays, multiple input multiple outputs with orthogonal frequency division multiplexing
(MIMO‐OFDM) provide better communication performance that can be applied to the fast …

We propose and demonstrate deep learning-based fast-orthogonal frequency division
multiplexing (FOFDM-DL) system for underwater optical wireless communications. FOFDM …

This article presents a developed intensity modulation/direct detection (IM/DD) optical
orthogonal frequency division multiplexing (O-OFDM). More precisely, the presented CO …
