An Acoustic OFDM System with Symbol-by-Symbol Doppler Compensation for Underwater Communication
We propose an acoustic OFDM system for underwater communication, specifically for vertical link communications such as between a robot in the sea bottom and a mother ship in the surface. The main contributions are (1) estimation of time varying Doppler shift using continual pilots in conjunction wit...
