Underwater acoustic (UWA) communication is an ongoing challenge because of the heavy
time spread by multipath and Doppler spreads. In this paper, we propose a UWA …

Underwater acoustic (UWA) communication in shallow water has been challenging owing to
multipath-induced signal distortion and motion-induced Doppler distortion. In this study, we …

Underwater acoustic (UWA) channels are wideband in nature due to the small ratio of the
carrier frequency to the signal bandwidth, which introduces frequency-dependent Doppler …

Underwater acoustic (UWA) channels are characterized by a severe spread in time and
frequency, and are usually labeled as “doubly spread channels.” In this paper, we propose …

In this paper, we propose a novel underwater acoustic (UWA) communication scheme that
achieves energy and spectrum efficiency simultaneously by combining Doppler-resilient …

Multicarrier modulation in the form of orthogonal frequency division multiplexing (OFDM) has
prevailed in recent broadband wireless radio applications due to the low complexity of …

In this study, we apply Doppler shift correction schemes for underwater acoustic (UWA)
communication with orthogonal signal division multiplexing (OSDM) to achieve stable …

Multicarrier techniques have made it possible to wirelessly transmit data at higher rates for
underwater acoustic (UWA) communication. Several multicarrier techniques have been …

Multiple-input-multiple-output (MIMO) techniques have been actively pursued recently in
underwater acoustic communications to increase the data rate over the bandwidth-limited …

In this paper, we propose a dominant Doppler compensation technique for single carrier
single input multiple output (SIMO) underwater acoustic communication. An initial pre …
