A novel approach for multipath channel estimation in CDMA networks using the Unscented Kalman Filter

The paper proposes a novel approach for time delay and channel gain estimation for multipath fading Code Division Multiple Access (CDMA) signals using the Unscented Kalman Filter (UKF). Given the nonlinear dependency of the channel parameters on the received signals in multiuser/multipath scenarios, we show that the UKF achieves better performance than its… CONTINUE READING
