1. IntroductionOne goal of 6G is to provide underwater wireless communications to global coverage [1]. Sound waves are considered the best carrier for underwater wireless communication [2,3,4]. Underwater acoustic (UWA) channels for 6G are characterized by frequency-selective fading due to the limited channel bandwidth, long transmission delay, and multipath [5].

1. IntroductionUnderwater biomimetic communication ensures the covertness of communication signals by mimicking the communication signals with the sounds of underwater organisms. The underwater biomimetic communication method has been researched to overcome the large, low-probability detection problem of the conventional direct sequence spread spectrum method in underwater communication [1,2,3,4,5,6,7].
