CA 2710139

Systems and methods disclosed herein generate pseudo pilot signals including PN phase offsets corresponding to a plurality of pseudo base stations. The pseudo base stations are (1) a plurality of non-physical base stations, and/or (2) physical base stations outside the reception range of the mobile device. The pseudo pilot signals are combined with communication signals from a physical base station to form a series of composite signals. The composite signals are transmitted for reception by a wireless mobile device and are used to determine the location of the mobile device.

L'invention concerne des systèmes et des procédés générant des signaux pseudo-pilotes incluant des déphasages PN correspondant à une pluralité de pseudo-stations de bases. Les pseudo-stations de base sont (1) une pluralité de stations de base non physiques et/ou (2) des stations de base physiques à l'extérieur de la portée de réception du dispositif mobile. Les signaux pseudo-pilotes sont combinés à des signaux de communication provenant d'une station de base physique pour former une série de signaux composites. Les signaux composites sont émis pour réception par un dispositif mobile sans fil et sont utilisés pour déterminer l'emplacement du dispositif mobile.
