Abstract

La présente invention porte sur une méthode permettant de disposer plusieurs faisceaux directionnels (61-64) dans un système de radio cellulaire comportant plusieurs antennes, chacune assurant la communication sur un secteur respectif correspondant. Le brouillage entre des secteurs géographiquement proches est réduit par la méthode, ce qui se traduit par une amélioration de la valeur du rapport porteuse/brouillage. Les fréquences porteuses de deux faisceaux intérieurs émis par une antenne sont échangés pour deux faisceaux intérieurs qui sont émis sensiblement dans la même direction par une autre antenne. Cette situation se traduit par une valeur porteuse/brouillage améliorée pour les quatre faisceaux émis par les antennes. Les techniques présentées s'appliquent à des systèmes à excitation par le centre ou à excitation par le coin (tricellulaires).
