SYSTEMS AND METHODS FOR LOCATING A MOBILE DEVICE |
摘要 |
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. |
