摘要： Techniques disclosed herein are directed toward make use of known wireless transmit station geometry (e.g., from a cell location database/almanac) to create an optimized search window, where the size of the search window is a function of an angle between a line from the center of the region of position uncertainty of the mobile device to the location of the reference transmit station, and a line from the center of the region of position uncertainty of the mobile device to the location of the remote transmit station. Techniques can be utilized for various types of wireless transmit stations not only in cell networks, but Global Navigation Satellite Systems as well.

摘要： A method and apparatus for performing signal correlation is described. In one example, portions of a pseudorandom reference code are multiplied with portions of a repeating code of the digital signal to produce a plurality of inner products. The plurality of inner products are then integrated over a period less than a period of the repeating code to produce a correlation result with a broadened frequency response. In another example, the digital signal is correlated with a pseudorandom reference code to produce a first correlation. The digital signal is then correlated with the pseudorandom code reference code to produce a second correlation. The first and second correlations are then used to determine first and second signal delays. The frequency shift of the digital signal is computed using a difference between the first and second signal delays over time.

摘要： The propagation time for propagation of a radio signal (93) from a radio transmitting station to a radio receiving station (91) is estimated based on calculated correlation values (102), calculated energy values (101) and a known energy value. The receiving station (91) receives a series of received signals (93) that respectively correspond to radio signaling bursts transmitted by the radio transmitting station. Each of the radio signaling bursts includes a known signaling sequence. The calculated correlation values (102) are indicative of correlations between the received signals and the known sequence, the calculated energy values (101) are calculated for the respective received signals, and the known energy value is the energy of the known sequence.

摘要： An improved method for determining the location of a user terminal with a high degree of accuracy. By repeating N times the basic active positioning measurement sets, a much better accuracy is reached that will be of value to the user. According to the method of the present invention, the user makes a position call (404). A position call prompts a gateway to establish a traffic channel (406) on which a positioning message (408) will yield the basic set of measurements: round-trip delay and round-trip Doppler in single-satellite positioning, and the addition of delay-difference and Doppler difference to a second satellite in two-satellite positioning. The accumulated measurements are used to determine position and theoretical error (410, 412). The call is terminated when an accuracy threshold is reached or a time limit has expired. The user terminal receives a position message or a failure message (416).

摘要： A location system for identifying locations of emitters (1) in a cellular telephone service area. Searching (4) identifies active emitters in the service area to find the coarse areas in which active emitters (1) are located, using selection criteria to designate one or more of the active emitters as selected emitters. Emitter signals are measured with a plurality of sensors (19) each sensor at a different location. Groups of the sensors are tasked, one group of tasked sensors for each corresponding selected emitter. Each tasked sensor takes a measurement on an emitter signal transmitted by the corresponding selected emitter. The measurements are processed (5) to determine the location of each selected emitter based on the measurements from the group of tasked sensors.
