摘　　要：针对基于机器学习的涡旋光束轨道角动量键控(OAM-SK)通信方案因数据的制备、训练所导致的通信耗时长、离线处理等问题,提出基于螺旋谱判决的水下涡旋光束OAM-SK通信方案。该方案通过对接收端处的涡旋光束光场直接进行螺旋谱计算,即可实现对其模式的识别,从而完成信息的传输。仿真结果表明,虽然所提方案可靠性略低,但是其极大地提高了通信系统的有效性。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 proposes 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 received 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.
