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.

水下声学（UWA）通信被广泛用于水下活动。为了在浅水中提供可靠的通信，必须进行沟通计划，以应对多恐怖分和多普勒传播的影响。为了在浅水中进行可靠的通信，在测试坦克和港口中都考虑了使用正交信号分级多路复用（OSDM）进行阵列处理的UWA通信的性能。发现拟议的计划比令人震惊的多路径环境下的现有方案可以实现最佳的沟通质量。解决多普勒差异是将来的一个问题。
