基于螺旋谱判决的水下涡旋光束OAM-SK通信仿真研究
Research on simulation of underwater vortex beam OAM-SK communication based on spiral spectrum detection
摘要
Abstract
Aiming at the issues of long communication delays and offline processing caused by data preparation and training in machine learning-based vortex beam orbital angular momentum-shift keying(OAM-SK)communication schemes,this paper pro-poses an OAM-SK communication scheme for underwater vortex beams based on spiral spectrum detection.This scheme enables the recognition of the mode of the vortex beam by directly performing spiral spectrum calculations on the optical field of the re-ceived vortex beam at the receiver end,thereby achieving information transmission.The simulation results show that although the proposed scheme has slightly lower reliability,it significantly enhances the effectiveness of the communication system.关键词
