<p>A signal is classified as one among a plurality of classifications by employing the autocorrelation (R(k)) (17,18,20,21) of a complex low-pass version of the signal ( gamma (n) (10-16), i.e., the complex autocorrelation (R(k)). The normalized magnitude (E(k)) (22) of the complex autocorrelation obtained at a prescribed delay interval, i.e., "lag", is compared (via 24) to predetermined threshold values to classify the signal as having one of a plurality of baud rates.</p> |
