The major constraint on the performance of orthogonal frequency division multiplexing
(OFDM) based underwater acoustic (UWA) communication is to keep subcarriers …

In this paper, we focus on the need for remote and robust underwater acoustic (UWA)
communication in shallow sea. A set of OFDM underwater acoustic communication …

This paper proposes an underwater acoustic QPSK/16QAM/64QAM OFDM communication
system with robust Doppler compensation. This system has OFDM receiver which …

This paper proposes an underwater acoustic OFDM communication system to transmit
image or movie data from deep see AUV etc. to surface ship. In order to mitigate Doppler …

The Orthogonal Frequency Division Multiplexing (OFDM) technique is an effective method
for suppressing multi-paths interference of underwater acoustic (UWA) channels. In this …

Underwater acoustic (UWA) communication is still a challenging area of research, as
methods to deal with large intersymbol interference and Doppler spread are needed. We …

Orthogonal frequency division multiplexing (OFDM) has prevailed in high speed underwater
acoustic (UWA) communications with obvious multipath effects. However, with the …

Mobile underwater acoustic (UWA) communication is still challenging, since the mobile
UWA channel is characterized by severe delay and Doppler spreads. In this paper, we …

Orthogonal frequency division multiplexing (OFDM) has drawn extensive attention in the
field of underwater acoustic (UWA) communication due to its advantages of high …

Due to multipath propagation and frequency selective fading, there are many obstacles for
reliable and high data rate underwater acoustic (UWA) communication. OFDM is an …
