摘要
Abstract
Encoding phase information on 1 090 MHz extended squitter (1090ES) signals is a promising technical method for next generation ADS-B systems, carrier frequency synchronization is the key technique for phase modulated 1090ES signals.An carrier fre-quency synchronization algorithm is proposed in this paper , based on frequency acquisition and phase error tracking loop , in which binary search tree method based on correlation decision between local signals and input reply signals is used to achieve frequency ac -quisition for large frequency offset signals and phase error tracking loop is used to achieve small frequency offset estimation and cor -rection.The simulation results show that this algorithm can be applied to the receiver system of phase modulated 1090ES.关键词
