Abstract

We consider adaptive modulation and coding (AMC) techniques for Phase Shift Keying (PSK) transmission schemes in underwater acoustic (UWA) channels. To select a particular modulation and coding scheme at the transmitter, we examine the use of two channel quality indicators (CQIs) as adaptation metrics: achievable information rate with i.i.d. Gaussian inputs and post-equalization SNR. We explore the use of these adaptation metrics through simulation and using data recorded during the recent AUVfest 2007 experiment. To evaluate AMC techniques for UWA communications, we have transmitted signals having a broad range of bit rates, obtained by varying the number of transmit elements, the modulation scheme, and the code rate. We present results demonstrating the feasibility of using our two channel quality indicators as adaptation metrics for choosing the modulation and coding scheme that achieves the highest rate supported by the available channel.
