在本文中，我们提出了一种新的水声通信方案，实现能量和频谱效率，同时结合多普勒弹性正交信号分复用（D-OSDM）和多输入多输出（MIMO）信令。我们提出了MIMO D-OSDM的发射机和接收机处理。我们评估了MIMO D-OSDM的性能，在仿真中具有较大的符号间干扰（60个符号）和多普勒扩展（最大多普勒频移为15 Hz）。仿真结果表明，MIMO D-OSDM实现了几乎相同的能量效率，而正常的D-OSDM的频谱效率增加了一倍。我们的结论是，MIMO D-OSDM可以成为一个可行的技术，实现可靠和有效的水声通信。
In this paper, we propose a novel underwater acoustic communication scheme that achieves energy and spectrum efficiency simultaneously by combining Doppler-resilient orthogonal signal division multiplexing (D-OSDM) and multiple-input multiple-output (MIMO) signaling. We present both the transmitter and receiver processing for MIMO D-OSDM. We evaluate the performance of MIMO D-OSDM in simulations with a large inter-symbol interference (60 symbols) and Doppler spread (maximum Doppler shift of 15 Hz). The simulation results show that MIMO D-OSDM achieves almost the same energy efficiency as normal D-OSDM while doubling the spectrum efficiency. We conclude that MIMO D-OSDM can become a viable technique that achieves reliable and effective UWA communication.
