摘要

轨道角动量（orbital angular momentum，OAM）作为一种新的调制自由度，能大幅度提高无线通信的频谱利用率。而基于均匀圆阵列（uniform circular array，UCA）的OAM通信系统要求收发端阵列静止并且完美对准，导致OAM难以实际应用。提出了基于OAM的波束管理，通过收发端波束扫描，确定最佳收发波束匹配，利用匹配波束通信。仿真结果证明该方案能有效解决由收发端阵列非共轴带来的系统性能下降问题。

Abstract

As a new modulated degree of freedom

orbital angular momentum (OAM) could greatly improve the spectrum utilization of wireless communication.However

the uniform circular array (UCA)-based OAM communication system requires the transceiver array to be static and perfectly aligned

which makes it difficult for OAM to be practically applied.A beam management method based on OAM was proposed

which determined the best beam matching by scanning the beam of receiver and receiver

and the matched beam was used to communicate.Simulation results show that the proposed scheme could effectively reduce the system performance degradation caused by non-coaxial of receiver and transmitter arrays.
