Abstract: A ranging system includes a time of flight subsystem including circuitry incorporated in a mobile node and a base station for generating a TOF signal between the mobile node and the base station, measuring the time taken for transmission of the TOF signal, and generating a TOF distance signal based on the measured time. An accelerometer, mounted in the mobile node, generates an accelerometer signal. A distance filter generates the distance estimate. The filter is configured to (i) initialize the value of a distance estimate signal based on the TOF distance signal, (ii) detect a human step based on variances in the accelerometer signal, and (iii) change the value of the distance estimate signal by a predetermined quantum only upon detection of the human step, the change being positive or negative depending on a direction of the TOF distance signal relative to the distance estimate signal.

Abstract: Methods, systems, and devices for channel estimation in a location tracking system are described. The methods, system, and devices may include tools and techniques for determining and/or designing perfect or semi-perfect sequences (including preamble sequences) for implementation in a location tracking system. Sequences having 2's exponent dimensionality, such as ternary sequences, may be determined and employed, which may help reduce implementation complexity and/or operating power consumption. Sequences may be determined using mean square error and/or maximum autocorrelation peak performance metrics.

Abstract: Disclosed is a method and apparatus for determining the location of a mobile station based on the locations of a group of nearby mobile stations. A mobile station implementing the method will engage in short-range wireless communication with nearby mobile stations to determine the location of the nearby mobile stations and the distances between it and each nearby mobile station. The mobile station will then apply triangulation or another algorithm to compute its own location based on the determined locations and distances of the nearby mobile stations. Further, a serving radio access network can assist by providing a trust-signal to the nearby mobile stations, with the nearby mobile stations then reporting their locations conditional upon their receipt of both the location query and the trust-signal.
