A beacon signal (313) is provided in a wireless communication system using a hybrid matrix (303) and an inverse hybrid matrix (306). Using an unused port of the hybrid matrix (303), the beacon signal (313) is combined with traffic signals (316) intended for users of the wireless communication system. The hybrid matrix (303) transforms beacon signal (313) and the traffic signals (316) into output signals that each contain a portion of the beacon signal (313) and the traffic signals (316). The outputs from the hybrid matrix (303) are amplified by amplifiers (315). The outputs from the amplifiers (315) are then inverse transformed by an inverse hybrid matrix (306). The inverse transform matrix (306) recombines the portions of the beacon signal (313) and the traffic signals (316) originally input to the hybrid matrix (303), and the resulting signals are transmitted using sector antennas (320) and a beacon antenna (323).

L'invention concerne un signal (313) balise, émis dans un système de communication hertzien utilisant une matrice hybride (303) et une matrice hybride inverse (306). Par le biais d'une ouverture non utilisée de la matrice hybride (303), le signal (313) de balise est combiné à des signaux (316) de trafic destinés à des utilisateurs du système de communication hertzien. La matrice hybride (303) transforme le signal (313) de balises et les signaux (316) de trafic en signaux de sortie, qui contiennent chacun une partie du signal (313) de balise et des signaux (316) de trafic. Les signaux de sortie émis par la matrice hybride (303) sont amplifiés par des amplificateurs (315). Les signaux de sortie des amplificateurs (315) sont ensuite transformés inversement par la matrice hybride inverse (306). La matrice (306) de transformation inverse recombine les parties du signal (313) de balise et des signaux (316) de trafic qui sont entrés au départ dans la matrice hybride (303), et les signaux obtenus sont transmis par des antennes (320) de secteur et une antenne (323) de balise.
