摘要： A novel system and method for a network overlay geolocation system operating in a host wireless communication system with repeaters (350a, 350b) is disclosed. Embodiments of the novel system and method enable the geolocation system to determine if signals being received by the geolocation system arrive directly from a target mobile appliance or if the signals are passing through a repeater (350a, 350b) and therefore are subject to a known time delay. Embodiments of the novel system and method provide a more accurate geolocation of mobiles served by repeater stations than capable in the prior art.

The wireless communication system has plural base stations defining a signal coverage area for communication with a mobile appliance and collects test and measurement data simultaneous on the forward and reverse links during standard geo-location processes. The wireless communication system also collects test and measurement data when the network overlay geolocation system is in an idle state.

摘要： A system and method is disclosed for determining the location of a mobile appliance using the reverse pilot channel provided in CDMA 2000 communication systems to determine an attribute (e.g., time of arrival, angle of arrival, time difference of arrival, received power level) of a reverse pilot signal at one or more wireless location sensors. A network overlay of wireless location sensors monitors the reverse pilot channel for a target mobile's reverse pilot signal. The monitored signal may be compared to a reference signal to determine a correlation and thereby determine an attribute of the target mobile's reverse pilot signal. The method may be performed independently from the communication system and without requiring retrieval of information bits from the mobile appliance. The reference signal may be generated from the unique long spreading code mask of the target mobile appliance which is typically a function of the ESN of the target mobile appliance.

摘要： A method for enabling a system to enhance the accuracy of a location estimate modifies weights in a weight matrix associated with receiver station measurements in parallel with successive refinements of the location estimate. In a typical location estimation scenario, several receiving stations simultaneously derive measurements of a signal from the emitter. Any one of these measurements is in general some function of the emitter location and the receiving station location. The aggregate of these measurements is often in excess of the minimum number of measurements required to provide an estimate of the emitter location. Where such an excess exists, the method proceeds by modifying the weights associated with the measurements in parallel with successive refinements of the location estimate. The method can be implemented over various cellular protocols with a consistent and significant enhancement in the accuracy of location estimates.

摘要： A method for calibrating an antenna and signal processing system enabling angle or arrival (AOA) determination for a frequency hopping signal, in which a calibration coefficient is determined in response to one or more calibration signals injected into the system at one or more of the frequencies in the hopping sequence and proximate in time to reception of the communication signal.

摘要： Embodiments of a system and method are disclosed that enable geo-location of a mobile appliance (20) communicating over a frequency hopping air interface for a network overlay geolocation system having plural wireless location sensors (30). The wireless location sensors (30) include a radio receiver channel capable of receiving the forward channels of the air interface transmitted from the base station (10) to the mobile appliance (20). The network overlay geo-location system of the present disclosure monitors these forward channels and measures parameters that allow the geolocation system to synchronize with the hopping of the air interface on the reverse channel. The plurality of sensors measure an attribute of a signal on the reverse channel to thereby enable geo-location. Synchronization can also be reference to a stable system clock and the plurality of sensors may be tuned in reference to the system clock to enable measurement of the frequency hopping reverse channel.

摘要： A novel system and method for a network overlay geolocation system operating in a host wireless communication system with repeaters is disclosed. Embodiments of the novel system and method enable a wireless communication system to determine if signals being received by system receivers arrive directly from a target mobile appliance or if the signals are passing through or via a repeater. In an embodiment, the system's repeaters use a co-channel AM Golay Hadamard sequence multiplied by an uplink signal to watermark the repeated signal. The system uses the known AM Golay Hadamard sequences of the repeaters and the waveform of the received uplink signal to detect whether a repeater has operated on the signal and which repeater operated on the uplink signal. Embodiments of the novel system and method provide system management data and can be used to provide more accurate geolocation of mobiles served by repeater stations.
