    Abstract: PROBLEM TO BE SOLVED: To provide methods and apparatus that may be used in identifying a location of a signal (such as a GPS signal) in a two-dimensional search space.
    SOLUTION: A method according to one embodiment includes obtaining a plurality of results by correlating a received code with a reference code. Each of the results corresponds to one of a plurality of code phase hypotheses and one of a plurality of frequency hypotheses. For each of the plurality of frequency hypotheses, a plurality of peaks are selected from among the results for the frequency hypotheses and a list on which the plurality of peaks selected are ordered is stored.

    Abstract: PROBLEM TO BE SOLVED: To provide systems, methods and apparatus for frequency control.SOLUTION: A receiver according to one embodiment includes a frequency control unit configured to receive a stream of samples including a plurality of received instances of a transmitted signal. The frequency control unit is configured to output a first correction signal (e.g. indicating a rotation) that is based on more than one of the received instances and a second correction signal (e.g. to control an oscillator) that is also based on more than one of the received instances. In some embodiments, a controlled oscillator is used to receive and/or transmit another signal, such as a signal received from a GPS space vehicle. In other embodiments, the received instances are from a GPS signal. In further embodiments, a fixed-frequency oscillator is used, and the second correction signal is used to receive and/or transmit another signal, such as a GPS signal.

    Abstract: A method according to an embodiment obtains a list of peaks for each of a number of frequency hypotheses. Each peak has an energy result and corresponds to a code phase hypothesis. Embodiments include methods and apparatus that may be used in identifying a location of a signal (such as a GPS signal) in a two-dimensional search space. Location information may be further applied to operations such as signal acquisition, signal tracking, position location of a receiver, and timing operations such as the synchronization of one or more other processes.

    Abstract: A method and device for managing a reference oscillator within a wireless device is presented. The method includes selecting reference oscillator parameters associated with the lowest reference oscillator error, where the selection is based upon reference oscillator parameters derived using different technologies within a wireless device, acquiring a satellite based upon the selected reference parameters, determining the quality of the satellite-based position fix, and updating the reference oscillator parameters based upon the quality of the satellite-based position fix. The wireless device includes a wireless communications system, a satellite positioning system (SPS) receiver, a reference oscillator connected to the wireless communications system and SPS receiver, and a mobile controller connected to the reference oscillator, SPS, and wireless communications system, and a memory connected to the mobile controller, where the memory stores a reference oscillator parameter table and instructions causing the mobile controller to execute the aforementioned method.

    Abstract: A forward link repeater delay watermarking (FLRDWM) system and method that enable accurate position location of mobile stations in areas where repeaters are present by watermarking repeated signals with repeater information. A repeater watermarks a forward link signal with a (unique or non-unique) time delay modulation waveform watermark every time a signal passes through the repeater. A mobile station detects and/or identifies the time delay watermark on the forward link signal to determine repeater information that aids the network position determination entity or mobile station position location system in determining position location using AFLT and/or A-GPS systems. A forward link time delay watermarking system can be implemented to achieve low impact on FL and AFLT performance, favorable detection and identification probabilities, and short time-to-detect/identify.
