A New Method for Eliminating False Lock in TT&C

Abstract:

False lock is a fatal problem in TT&C due to the inevitable excessive delay.It can lead to false carrier acquisition.Based on the knowledge that false lock will not occur in the fast capture bandwidth,a new method for eliminating false lock is proposed.The carrier recovery loop closes only when the uplink carrier signal is detected in fast capture bandwidth by using signal detector and lock detector,then the false lock can be avoid.Compared with traditional methods,this solution is easier to realize and suitable for any type of loop. The experimental results reveal that the proposed method can eliminate false lock effectively.
