Synchronization of receiver for decoding automatic dependent surveillance broadcast signals
The proposed research investigates the design of a receiver to decode ADS-B signals. After the ADS-B data has been detected by the receiver the bits are decoded base on the message type and format. The format must be known to ensure the correct bits are used for altitude, latitude, longitude and air...

The proposed research investigates the design of a receiver to decode ADS-B signals. After the ADS-B data has been detected by the receiver the bits are decoded base on the message type and format.

DF17 message format is used to give an interpretation for the individual components of the message. To ensure correct detection of data, the receiver should use the preamble to detect the received ADS-B. Preamble sequence method was used previously to detect the wanted preamble. Correlation method used on a simulator before implement on the Software Defined Radio to check the ability of detecting the preamble at the correct time.
