More Information
Summary: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.
