| Abstract | An All-Lag Correlator Is Provided That Correlates A Received Spread-Spectrum Signal With A Reference Code And Produces At Each Sampling Instance N Correlation Lags Corresponding To The Correlation Of The Received Signal With 0, 1, . . . , N-1 Lags (Or Delays) Of The Reference Code, Wherein N Is The Length Of The Reference Code. The Correlator Includes A Spread Spectrum Signal Storage Means, Subtraction Means, Multiplication Means, Correlation Lag Storage Means And Addition Means Configured Such That A Correlation Lag For A Present Sampling Instance Is Based On A Correlation Lag Of A Previous Sampling Instance. |
