A transmitter (300) is utilized to provide wireless communication in a sectorized coverage area. The transmitter (300) incorporates a hybrid matrix (303) and an inverse hybrid matrix (306) to combine input control signals (315) and traffic signals (316). The hybrid matrix (303) transforms the control signals (315) and traffic signals (316) into output signals which each contain a portion of the control signals (315) and traffic signals (316). The outputs from the hybrid matrix (303) are amplified by amplifiers (319), and the outputs from the amplifiers (319) are then inverse transformed by the inverse hybrid matrix (306). The inverse transform matrix (306) recombines the portions of the control signals (315) and traffic signals (316) originally input to the hybrid matrix (303), and the resulting signals are transmitted to mobile stations (203-205 and 208) in sectorized coverage areas (S1A and S1B) using sector antennas (320).

L'invention porte sur un émetteur (300) assurant des communications sans fil dans des zones de couverture découpée en secteurs. Ledit émetteur (300) comporte une matrice hybride (303) et une matrice hybride inverse (306) pour combiner les signaux de commande d'entrée (315) et les signaux de trafic (316). La matrice hybride (303) transforme les signaux de commande (315) et les signaux de trafic (316) en signaux de sortie contenant chacun une portion des signaux de commande (315) et de trafic (316). Les signaux de sortie de la matrice hybride (303) sont amplifiés par des amplificateurs (319), puis les signaux de sortie des amplificateurs (319) subissent une transformation inverse par la matrice hybride inverse (306). La matrice de transformation inverse (306) recombine les portions des signaux de commande (315) et de trafic (316) introduits à l'origine dans la matrice hybride (303), et les signaux résultants sont transmis à des stations mobiles (203-205 et 208) dans les zones de couverture (S1¿A? et S1¿B?) découpées en secteurs à l'aide d'antennes (320) de secteurs.
