A direct decoder method for OFDM with carrier frequency pilot in underwater acoustic communication systems
A direct decoder method for OFDM with carrier frequency pilot in underwater acoustic communication systems
In this paper, we propose a new decoder method at the receiver of system to compensate Doppler frequency shift for OFDM-based underwater acoustic communication systems. At the transmitter, in order to save bandwidth, we do not use additional signal header (preamble) in each OFDM frame as proposed in many conventional approaches.
