Research on High Speed Underwater Acoustic Communication Based on Orthogonal Frequency Division Multiplexing

Deng Hong-chao

Abstract

OFDM(orthogonal Frequency division multiplexing) is suitable for communication in multi-path fading and limited bandwidth channel.In this paper,a high speed underwater acoustic communication system based OFDM is proposed.A method is given for synchronization and channel estimation.The effectiveness of the system is experimentally tested at sea.
