发明名称 Apparatus and method for CDMA time pseudolite for repeater identification
摘要 Apparatus and method for resolving repeater location ambiguities in a CDMA network using a CDMA Time Pseudolite. The CDMA Time Pseudolite includes a CDMA receiver to receive a CDMA signal with an embedded CDMA timing, a baseband processor to extract the CDMA timing and to adjust the CDMA timing to derive a signal with GNSS-like timing; and a GNSS transmitter to generate a GNSS-like signal and to transmit the GNSS-like signal to a mobile station. In one embodiment, the CDMA Time Pseudolite is situated at or nearby a CDMA signal repeater so that a mobile station may unambiguously identify a received CDMA signal as being transmitted by a particular CDMA signal repeater and then using that received CDMA signal for position determination of the mobile station.
