Abstract: One embodiment is directed towards an RF receiver for receiving a pulse-position modulated signal transmitted with a 1090 MHz ADS-B transmitter, wherein the pulse-position modulated signal is preceded by a preamble of 4 pulses that conform to an ADS-B protocol. The receiver can filter a digital sample stream with a filter matched to pulses in an earlier half of an expected preamble sequence to produce a first matched filter output sample stream. The receiver can also filter the digital sample stream with a filter matched to a pulses in a latter half of the expected preamble sequence to produce a second matched filter output sample stream. The receiver can determine that a sequence of pulses match the expected preamble sequence based on when the first matched filter output sample stream and the second matched filter output sample stream are above a minimum trigger level at the same time.
