Abstract

In this contribution a novel particle filter based two-step automatic frequency control (AFC) scheme is proposed, which is used for non-cooperative receiver in the Low earth orbit (LEO) satellite communication system. The proposed AFC scheme employs particle filter techniques to implement both coarse and fine carrier estimations. Our study shows that the proposed AFC scheme is capable of achieving better Root-Mean Square (RMS) frequency error performance than extended kalman filter (EKF) based AFC scheme in non-Gaussian environment, but with less preamble symbols, which is suitable for burst packet receiving.
