Abstract
A recent time reversal experiment demonstrated that multiple foci can be projected from an array of sources to the same range but at different depths. This "multiple-input, multiple-output (MIMO)" process potentially can increase the information data rate. This paper presents experimental results of coherent communications (BPSK, QPSK, and 8-QAM) at 3.5 kHz with a 1 kHz bandwidth where different messages were sent simultaneously to different depths at 9 km range in 1110-m deep shallow water
