Abstract: A wireless device includes a first circuit to transmit wireless Wi-Fi and/ or Bluetooth signals, a second circuit to receive satellite signals, a third circuit to transmit cellular signals and a processor. The processor is adapted to selectively adjust a transmission rate of the wireless signals in response to a comparison between a first priority value assigned to the wireless Wi-Fi and/or Bluetooth signals and a second priority value assigned to the satellite signals. The processor may also monitor one or more operational parameters associated with the wireless Wi-Fi and/or Bluetooth signals, and in response thereto dynamically adjust one or both of the first and second priority values.

Abstract: Techniques are provided which may be implemented using various methods and/or apparatuses in a receiver and/or other like device to determine an SPS time using SPS signals based on a correlation process. A verification process may be performed, for example, that verifies a maximum peak in comparison with other peak information resulting from the correlation process, for example, by considering a ratio of a maximum peak to a next maximum peak. A time-setting algorithm may be selected, for example, based, at least in part, on a time uncertainty and/or on a type of demodulation performed on the SPS signal. The time-setting algorithm may operatively control one or both of the correlation and/verification processes in a desired manner given the time uncertainty and/or type/mode of demodulation performed.

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.
