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 …

This paper is focused on the characteristics of underwater acoustic communication channels
and their implications on the design of bandwidth efficient modulation and demodulation …

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

In this paper, we propose a new method to compensate Doppler frequency shift for OFDM-
based underwater acoustic communication systems. In order to save bandwidth, we do not …

In this research, effects of a multipath signal with a nonuniform Doppler shift on underwater
acoustic communication between surface and underwater vehicles are investigated by …

For the high peak-to-average power ratio and the sensitivity of orthogonal frequency division
multiplexing system to Doppler shift, a single carrier underwater acoustic (UWA) …

수중에서는 매질과 채널의 특성으로 인해 가능한 최대 데이터 전송 속도는 지상통신에서의
데이터 전송 속도에 비해 매우 낮으며, 이를 어떻게 극복하느냐가 매우 중요하다. 특히 천해 …

The Orthogonal Frequency Division Multiplexing (OFDM) scheme has attracted attention
recently in underwater acoustic communications, due to its robustness in dispersive …

Underwater acoustic (UWA) channels brings frequency-dependent Doppler shifts. In this
paper, we treat the channel as having a common Doppler scaling factor on all propagation …
