Performance of PN Tracking with Extended Kalman Filter

Extended Kalman Filter기반의 PN부호 추적성능

In this paper, a PN code tracking loop with extended Kalman filter (EKF) is proposed for a direct-sequence spread-spectrum. EKF is used to estimate amplitude and delay in a multipath fading channel. It is shown that tracking error performance is significantly improved by EKF compared with a conventional tracking loop.
