Field tests of adaptive modulation and coding for underwater acoustic OFDM

Published: 11 November 2013 Publication History

Abstract

Adaptive modulation and coding (AMC) technique can be applied in underwater acoustic communications to improve the system data rate as well as the robustness in varying channel conditions. In this paper, we demonstrate an OFDM based AMC operation using a number of transmission modes with different data rates. We propose to use the effective signal-to-noise ratio (SNR) computed after channel estimation and channel decoding as performance indicator for mode switching, instead of input SNR and pilot SNR. Real time AMC tests have been conducted in a recent sea experiment.
