Research and Improvement of Pilot Synchronization Algorithm for ADS-B System
In the ADS-B receiving module,the detection peak value of low-power signal matching filter output signal is low,and the packet receiving error rate is high.To solve the problems,the pilot synchronization algorithm is studied and improved.Through theoretical analysis,the parameters of the matched filter are reasonably designed to improve the receiving performance,and the leading pulse sequence detection method based on cross-correlation detection is verified.The time delay model of the matched filter cross-correlation detection is optimized so that the sampling time is the maximum.The simulation results show that,compared with the original module-matched filter,the designed filter can effectively increase the peak value at low power and reduce the packet error rate.
