Abstract
A method for processing a signal derived from a radio frequency signal at some rate in a range of allowable data rates according to one embodiment includes downconverting an incoming signal derived from a radio frequency signal to complex near-baseband signals; processing the complex near-baseband signals in two data correlators corresponding to data 0 and data 1; and changing effective lengths of the correlators based on a symbol data rate of the incoming signal. Such methodology may also be implemented as a system using logic for performing the various operations. Additional systems and methods are also presented.
