AbstractThis paper presents a Kalman filtering channel estimator for wireless multicarreir code-division multiple access (MC-CDMA) communication systems. Joint Kalman filter and Kalman filter per-subcarrier schemes are employed to track the time-varying channel. Pilot symbols are equally-placed in the training subcarriers for channel estimation. The proposed pilot-aided channel tracking scheme presents better performance than the decision-directed method in the case of high fading rate. The robustness of the Kalman filter is also studied when the fading rate is unknown. Numerical simulations illustrate the performance of the proposed pilot-aided channel estimator. © 2005 IEEE.
