Description

technical field [0001] The invention belongs to the technical field of underwater network information system application. Background technique [0002] Since electromagnetic waves are severely attenuated when propagating in water, and sound waves are the only form of energy known to mankind so far that can travel long distances in water, detection, communication, positioning, navigation and identification in the ocean are mainly realized by using sound waves. Therefore, the research on the integrated waveform optimization of underwater communication positioning and identification mainly focuses on the research on underwater acoustic communication, positioning and identification. [0003] Underwater acoustic communication technology has experienced the development process from analog communication stage to digital communication, and it is mainly divided into two categories: non-coherent modulation and coherent modulation. Non-coherent modulation has obvious advantages in ant...
