Abstract
A method for mitigating inter-mode interference (IMI) caused by antenna misalignment in an orbital angular momentum (OAM) mode multiplexing (OAM-MM) system and detecting a signal in an OAM beam. The method includes receiving an OAM beam bearing a signal, determining a phase-shifting value based on at least one of a type of the antenna misalignment and one or more antenna-misalignment parameters, wherein the phase-shifting value belongs to a beamforming (BF) codebook, shifting the phase of the received OAM beam using the determined phase-shifting value, and detecting the signal from the phase-shifted OAM beam.
