Abstract:
A carrier phase offset estimator is presented,which is based on extended Kalman filter (EKF) and for multi-carrier code division multiple access (MC-CDMA) systems. The proposed technique depends on non-synchronized sampling rate while no pilot is required to transmit. An equivalent state space model is also derived for phase error and then extended Kalman filter method is used for tracking.
