Abstract

A signal detector and classifier for signals having inherent event periodicity such as digital modulations. Basically, the invention involves passing a band of frequencies through a plurality of paths of different or variable delay, combining pairs of bands having different delay, Fourier transforming or filtering the results of the combining to produce signals having magnitudes and phases related to received signal content. Frequency, symbol rate, and symbol phase are determined. Similar stages may be cascaded to detect higher orders of modulation. The invention also detects hybrid modulation. Interstage filtering of decreasing bandwidth enhances the performance of this invention. Novel ambiguity transform circuits are disclosed.
