摘要： A system and method for estimating a location of a wireless device receiving signals from a plurality of nodes of a communication system. A first value may be determined based on a network timing characteristic for one of the nodes, and a second value may be determined based on a network measurement report characteristic. An observed time difference of arrival (“OTDOA”) hyperbola may then be calculated based on the first and second values, and a location of the wireless device estimated as a function of the OTDOA hyperbola.

摘要： A system and method for estimating the location of a mobile station that receives signals from a plurality of base stations. The base station timing offsets may be estimated utilizing an observed time difference of arrival value at the mobile between a first signal received from a first base station and a second signal received from a second base station. An initial location for the mobile is randomly selected and an estimated location is determined using the selected initial location, the observed time difference of arrival value, and an iterative search algorithm. The estimated location may be stored if the estimated location is within a predetermined area. In addition, for each such estimated location, the applicable base station time offsets that relate to this location may be updated to generate a current best estimate. A calculated location for the mobile may be determined from stored estimated locations and the current base station time offset estimates.

摘要： A method for calibrating an antenna and signal processing system enabling angle of 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. The calibration coefficients are reflective of a frequency and time dependent parameter of a path between the antenna and wireless location sensor. The AOA is determined as a function of the calibration coefficient and the radio frequency energy of the received communication signal. Several embodiments of the method are illustrated.

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.

摘要： A method is described that enables a system to estimate the individual times of arrival of multi-path signals components in a received signal while blind to the particular angular response characteristics of an antenna array. Additionally, a system is described that estimate the impulse response of the modulation channel. The impulse response is used to generate impulse response estimates for all multi-path signal components without reference to the actual angle of arrival of the signal. The impulse response for the multi-path constituents are directly associated with the time delays on each path, providing delay estimates for each path.
