An Algorithm to Separate 1090ES ADS-B Signals

Abstract:

Multiple 1090ES ADS-B signals may be overlapped in the receiver systems on the ground. At the same time, 1090ES ADS-B signals may be interfered by A/C replies with the same carrier frequency. To address these problems, firstly, principle component analysis (PCA) is employed to pre-whiten the observed signals in order to reduce the relevance between signals. Then extended projection algorithm (EPA) is applied to separate 1090ES ADS-B signals. Effect of the separated signal is verified by simulation. The performance of this algorithm is also analyzed in several aspects. Simulation results show that this algorithm not only can succeed in separating multiple 1090ES ADS-B signals effectively but also has both higher precision and strong ability of stability.
