A Timing Synchronization Method Applicable to Low Frequency Communication System

Abstract

Aiming at the difficulty in the high-precision timing synchronization of MSK signal in low frequency communication system, this paper analyzed and compared several timing synchronization methods and timing parameter estimation algorithms, and proposed an improved timing synchronization method combining ML forward estimation and feedback loop. According to the simulation result, compared with traditional feedback algorithms, the improved synchronous method has advantages in such aspects as capture time and estimation accuracy.
