Abstract:
In one implementation, a receiver has a module to detect a carrier within a portion of a digital representation of a received signal. In addition, the receiver includes a module to calculate the cross-correlation between the portion of the digital representation of the received signal and a reference signal representing an expected pulse pattern. The receiver also has a module to generate an estimate of a portion of a message potentially included in the digital representation of the received signal. The receiver further includes a screening module to generate a feature vector representing the estimated message, project the feature vector into a feature space, and determine the likelihood that the digital representation of the received signal includes a message. If the digital representation of the received signal likely includes a message, the receiver includes a non-coherent matched filter to recover the message from the digital representation of the received signal.

Claim (Index 20):
A method for recovering a 1090 MHz Mode S Extended Squitter (\u201cES\u201d) ADS-B message from a received signal comprising:\n determining if it is likely that a received signal includes a frequency component within a range of 1090 MHz; comparing at least part of the received signal to a model of at least part of an expected 1090 MHz Mode S ES ADS-B message; determining if it is likely that the received signal includes a 1090 MHz Mode S ES ADS-B message based on a result of comparing the part of the received signal to the model of the part of the expected 1090 MHz Mode S ES ADS-B message; detecting multiple features of at least part of the received signal; comparing the detected features of at least part of the received signal to characteristic features of at least part of a 1090 MHz Mode S ES ADS-B message; determining if it is likely that the received signal includes a 1090 MHz Mode S ES ADS-B message based on a result of comparing the detected features of at least part of the received signal to characteristic features of at least part of a 1090 MHz Mode S ES ADS-B message; and implementing a non-coherent filter configured to recover a 1090 MHz Mode S ES ADS-B message from the received signal following a determination that it is likely that the received signal includes a frequency component within a range of 1090 MHz, a determination that it is likely that the received signal includes a 1090 MHz Mode S ES ADS-B message based on the result of comparing the part of the received signal to the model of the part of the expected 1090 MHz Mode S ES ADS-B message, and a determination that it is likely that the received signal includes a 1090 MHz Mode S ES ADS-B message based on the result of comparing the detected features of at least part of the received signal to characteristic features of at least part of a 1090 MHz Mode S ES ADS-B message.
