Abstract
We investigate the performance of turbo coded multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems with layered space time (LST) architectures for underwater acoustic (UWA) channels. We present results obtained by processing data from the AUVfest07 experiment performed in June 2007. We review the necessary components of a MIMO-OFDM communication system, including time/frequency synchronization and channel estimation, and we summarize modifications needed to make the system suitable for UWA channels. We find that the results of the AUVfest 2007 experiment are very promising in terms of achieved data rates and error rate performance of the system. We also present results for differential MIMO-OFDM modulation techniques, that potentially would provide additional robustness in more difficult channels.
