Underwater acoustic (UWA) communication is widely used for underwater activities. To provide reliable communication in shallow water, communication scheme to cope with the effects of multipaths and Doppler spread is necessary. To conduct reliable communication in shallow water, performance of UWA communication using orthogonal signal division multiplexing (OSDM) with array processing was considered in both a test-tank and a harbor. It was found that the proposed scheme could achieve the best communication quality than existing schemes under heady multipath environment. Addressing Doppler spread is an issue in the future.

水声通信在水下活动中有着广泛的应用。为了在浅水环境中提供可靠的通信，需要一种能够有效地科普多径效应和多普勒效应的通信方案。为了在浅水环境下进行可靠的通信，在试验水池和港口中研究了采用正交信号分复用（OSDM）和阵列处理的水声通信性能。结果表明，在强多径环境下，该方案可以获得比现有方案更好的通信质量。解决多普勒扩展是未来的一个问题。
