Abstract:
1. A parameter estimator comprising: correlation logic for determining a correlation function representing a correlation between a signal and one or more shifted versions of an identification code; and analysis logic for analyzing the correlation function to determine whether one or more first peak(s) are distinguishable from one or more sidelobe(s) of a second peak responsive to a threshold dependent on a noise floor, estimating one or more parameter(s) relating to the signal responsive to the one or more first peak(s) when the one or more first peak(s) are present and are distinguishable from the sidelobe(s) of the second peak, and estimating the one or more parameter(s) responsive to the second peak when the one or more first peak(s) are not present, or, when present, are not distinguishable from the sidelobe(s) of the second peak.
