摘要

本文基于电磁信息理论，提出了一种适用于轨道角动量正交通信系统的通用偏弧正交接收（GPAOR）理论。首先，根据天线的有效自由度定义了多模OAM集正交接收的概念；在此基础上，推导了采用部分弧采样法保持模态正交性的充分必要条件。本工作完善了现有的OAM部分弧采样接收（PASR）理论，提出的正交接收条件对连续和离散空间采样接收均有效。

Evolution of Partial Arc Sampling Receiving Theory for Orbital Angular Momentum-Based Communications

In this letter, we propose a general partial arc orthogonal receiving (GPAOR) theory based on the electromagnetic information theory for orbital angular momentum (OAM) orthogonal communication systems. Firstly, the concept of orthogonal receiving for multi-mode OAM set is defined based on antennas’ effective degree of freedom (EDoF). Subsequently, the necessary and sufficient conditions for maintaining the orthogonality between OAM modes using partial arc sampling method are derived. This work completes the existing OAM partial arc sampling receiving (PASR) theory, and the proposed orthogonal receiving condition is valid for both continuous and discrete spatial sampling receiving.

期刊介绍： The IEEE Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of communication over different media and channels including wire, underground, waveguide, optical fiber, and storage channels. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of communication systems.
