最近的一项时间反演实验表明，多个焦点可以从一组源投射到同一范围但不同深度。这种“多输入多输出（MIMO）”过程潜在地可以增加信息数据速率。本文介绍了在1110米深的浅水中，在9 km范围内，以3.5kHz和1 kHz带宽将不同信息同时发送到不同深度的相干通信（BPSK、QPSK和8-QAM）的实验结果
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
