Abstract: The Automatic Dependent Surveillance-Broadcast (ADS-B) is a proven technique for aviation control. ADS-B systems periodically transmit the aircraft position, aircraft ID, aircraft velocity and other information on the 1090MHz. Space based ADS-B uses low earth orbit satellites that can achieve global surveillance. A large number of aircrafts will make ADS-B signals overlap more frequently at the receiver, which seriously reduces the decoding efficiency of the receiver. In this paper, we first analyze the collision model, and point out that the one order overlap situation is the most serious in all cases of signal overlap. In this paper, we use the JADE algorithm to separate the one order overlap signals successfully. The experiments show that compared with the traditional decoding algorithm, the decoding accuracy is significantly improved and the decoding efficiency of the receiver is obviously improved after separating the mixed signal.
