1. A method for processing a signal derived from a radio frequency signal at some rate in a range of allowable data rates, the method comprising:

  • 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,wherein each correlator includes a series of windowed integrators that are configurable for different lengths.
