文章阐述了在高速水声通信中的最新研究成果。-This paper presents a review of

recent results and research problems in high-speed underwater

acoustic communications, focusing on the bandwidth-efficient

phase-coherent methods. Experimental results are included to

illustrate the state-of-the-art coherent detection of digital signals

transmitted at 30 and 40 kbls through a rapidly varying one-mile

shallow water channe
