The Unscented Kalman Filter (UKF) does not approximate the nonlinear system with a linear model as the Extended Kalman Filter (EKF) does, so estimation of channel coefficient and time-delay in CDMA transmit channel by UKF algorithm is more accurate than EKF.
UKF算法能够避免EKF由于线性化非线性系统而带来的误差过大等问题,比EKF估计的更加精确。
