Description

一种轨道角动量OAM模态切换方法、装置、设备及存储介质 技术领域
本公开涉及通信技术领域，尤其涉及OAM模态切换方法、装置、设备及存储介质。
背景技术
为了解决频谱资源短缺的问题，通常会利用UCA(Uniform circular array，均匀圆形相控天线阵列)来建立OAM(Orbital angular momentum，轨道角动量)通信***。但是，基于UCA的OAM通信***中，由于信道环境是动态变化的，因此为保证传输性能，收发端传输所用的OAM模态也需要进行切换。
相关技术中，当收发端需要切换OAM模态时，信号发送端会向信号接收端发送所要切换的OAM模态的指示信息，并切换至该OAM模态。以及，信号接收端接收到该指示信息后，会解调译码该指示信息以确定出所要切换的OAM模态，并切换至该OAM模态。
但是，相关技术中，信号接收端完成指示信息的解调译码需要一定的时间，并且，不同的信号接收端的解调译码的能力会有所不同，从而会使得信号接收端从接收到切换信令到完成模态切换存在切换时延。因此亟需一种OAM模态切换方法，以避免由于信号接收端的切换时延导致的发射端与接收端模态不同步。
