Kalman filter for channel estimation in OFDM system an overview

This paper reviews published Kalman filtering algorithm used for channel estimation in OFDM system. By using this method, the fading channel can be greatly compensated. Here several different situations: the UWB OFDM system, MIMO-OFDM system and OFDM system with fast fading channel are described. The Kalman filter is detailed into IMM based Kalman filter, QRD&#..
