Title (EN) PROVIDING COMMUNICATIONS COVERAGE USING HYBRID ANALOG/DIGITAL BEAMFORMING
(FR) FOURNITURE D'UNE COUVERTURE DE COMMUNICATION À L'AIDE D'UNE FORMATION DE FAISCEAU ANALOGIQUE/NUMÉRIQUE HYBRIDE
Abstract:
(EN) An apparatus includes feeds to form analog beams. The feeds are divided into panels. The apparatus includes processing circuitry that divides a target area for communications coverage into regions, including a first region and a second region neighboring each other. The processing circuitry generates, for the first region, a first plurality of analog beams, forming a first cluster. The processing circuitry generates, in the first cluster from the first plurality of analog beams, a first plurality of hybrid beams arranged in a first arrangement in the first cluster. The processing circuitry generates, for the second region, a second plurality of analog beams, forming a second cluster. The processing circuitry generates, in the second cluster from the second plurality of analog beams, a second plurality of hybrid beams arranged in a second arrangement that is adjacent to the first plurality of hybrid beams in the first arrangement.
(FR) Un appareil comprend des alimentations pour former des faisceaux analogiques. Les alimentations sont divisées en panneaux. L'appareil comprend un ensemble de circuits de traitement qui divise une zone cible pour une couverture de communication en régions, comprenant une première région et une seconde région se trouvant à proximité l'une de l'autre. L'ensemble de circuits de traitement génère, pour la première région, une première pluralité de faisceaux analogiques, formant un premier groupe. L'ensemble de circuits de traitement génère, dans le premier groupe à partir de la première pluralité de faisceaux analogiques, une première pluralité de faisceaux hybrides agencés dans un premier agencement dans le premier groupe. L'ensemble de circuits de traitement génère, pour la seconde région, une seconde pluralité de faisceaux analogiques, formant un second groupe. L'ensemble de circuits de traitement génère, dans le second groupe à partir de la seconde pluralité de faisceaux analogiques, une seconde pluralité de faisceaux hybrides agencés dans un second agencement qui est adjacent à la première pluralité de faisceaux hybrides dans le premier agencement.
