Abstract
A method for estimating a strength of a radio frequency signal according to one embodiment includes receiving a correlator magnitude signal from a correlator module; performing a gain scaling on the correlator magnitude signal; and averaging the scaled correlator magnitude signal or value associated therewith to generate an output indicative of a strength of the signal. Such methodology may also be implemented as a system using logic for performing the various operations. Additional systems and methods are also presented.
