Abstract[English]
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.[French]
L’invention concerne un procédé permettant d’atténuer une interférence inter-mode (IMI) provoquée par un désalignement d'antenne dans un système de multiplexage de mode (OAM-MM) de moment angulaire orbital (OAM), ainsi que de détecter un signal dans un faisceau OAM. Le procédé consiste à : recevoir un faisceau OAM portant un signal, à déterminer une valeur de déphasage d’après un type du désalignement d'antenne et/ou un ou plusieurs paramètres de désalignement d'antenne, la valeur de déphasage appartenant à un livre de codes de formation de faisceau (BF) ; décaler la phase du faisceau OAM reçu à l'aide de la valeur de déphasage déterminée ; et détecter le signal du faisceau OAM déphasé.
