Abstract

La présente divulgation concerne un procédé et un appareil de formation de faisceaux, un dispositif, et un support d'enregistrement. Le procédé consiste à : déterminer un premier vecteur de formation de faisceaux correspondant à chaque unité de réseau dans un réseau de transmission d'une extrémité de transmission, un premier vecteur de formation de faisceaux étant utilisé pour régler le sens de faisceau de transmission de l'unité de réseau, de telle sorte que le sens du faisceau transmis par chaque unité de réseau est réglable ; déterminer un second vecteur de formation de faisceaux correspondant à chaque unité de réseau, le second vecteur de formation de faisceaux étant utilisé pour former un faisceau de moment angulaire orbital (OAM) ; et réaliser une formation de faisceaux sur un signal transmis sur la base du premier vecteur de formation de faisceaux et du second vecteur de formation de faisceaux. Selon le procédé prévu par la présente divulgation, une divergence de faisceau de transmission est empêchée et l'angle de divergence du faisceau de transmission est réduit, de telle sorte que le problème selon lequel, « en raison de la caractéristique de divergence d'un faisceau OAM, des réseaux UCA d'extrémité de réception de différentes tailles doivent être conçus pour différentes distances de transmission » est évité. Par ailleurs, les coûts de fabrication sont réduits, et le problème selon lequel un système OAM ne peut pas être transmis à distance en raison de l'angle de divergence est également résolu.
