ABSTRACT
The traditional method of capturing a non-repetitive spread spectrum signal is by digitizing it's waveform.
This paper describes an alternate and more efficient method based on digitizing the phase progession of
the signal using counters which can be read on-the-fly. By curve-fitting the data, both carrieres) and
modulation, including FSK, PSK, Chirp and AGILE, can be recovered.
