Abstract
This paper proposes a new carrier tracking loop based on Extended Kalman Filter (EKF) with no data aided in low Signal-to-Noise Ratio (SNR) and high dynamic environment. It utilizes the outputs of accumulator after symbol decision as the observation matrix of EKF. With this method, the restriction generated by using discriminators in low SNR can be avoided. The simulations show that the structure proposed has excellent characteristics compared with Phase Lock Loop (PLL) and linear Kalman Filter (KF) assisted with phase discriminator.
