摘要： The subject matter disclosed herein relates to a system and method for estimating a location of a mobile station based, at least in part, on one or more measurements obtained from the mobile station based at least in part on one or more signals received by the mobile station from one or more signal sources. Such measurements may be combined based, at least in part, on estimates of measurement errors associated with the signal sources. In a particular implementation, such error estimates may be updated to account for changes in an operational environment.

摘要： 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.

摘要： Methods and apparatus are directed to mobile devices utilizing motion and/or position sensors for improving operating performance and/or power efficiency. In one example, a method for reducing power consumption in a mobile device includes receiving movement information, establishing movement data based on the movement information, determining if the mobile device is stationary using the movement data; and reducing the frequency of searching for a base station when the mobile device is stationary. In another example, a mobile device which reduces power consumption based upon movement data includes an RF front end, a receiver coupled to the RF front end, a data demodulator coupled to the receiver, a searcher, coupled to the RF front end and the receiver, which searches for base stations, and a processing unit coupled to the searcher, wherein the processing unit controls the searcher based upon the stationarity of the mobile device.
