摘要

水声信道具有丰富的多径散射特性，为MIMO通信的应用提供了良好的环境。然而，对于典型的水下通信信道，存在与大分数带宽、显著的多普勒色散和以秒为单位测量的延迟相关的困难。我们利用模拟和实验数据估计了典型浅水MIMO信道的信道容量，并激发了特定的波束形成算法来应对困难的声环境。

Underwater acoustic MIMO channel capacity

The underwater acoustic channel is rich in multipath scattering, making it a promising environment for the application of MIMO communications. However, for typical underwater communications channels, there are difficulties associated with the large fractional bandwidths, significant Doppler dispersion and latencies measured in seconds. We use simulated and experimental data to estimate the channel capacity for typical shallow water MIMO channels, and motivate particular beamforming algorithms which cope with the difficult acoustic environment.
