APPAREIL ET PROCEDE PERMETTANT DE FOURNIR DES COMMUNICATIONS SANS FIL A UNE ZONE DE COUVERTURE SECTORISEE

摘要

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).
