From: Kalman interpolation filter for channel estimation of LTE downlink in high-mobility environments
BER performance comparison at 200 km/h (A0 denotes a perfect channel estimation algorithm where the actual CFR is known to the receiver). Blue solid line with triangle: the BER performance of LS method.Red solid line with star: the BER performance of the proposed EKF method. Blue solid line with circle: the BER performance of the LMMSE method. Blue solid line with square: the BER performance of the perfect channel estimation method. The perfect channel estimation means that the actual CFR is known to the receiver.
