Abstract: Channel estimation is a major issue in communication system. In this paper, we propose a new idea for channel estimation that uses a Kalman Filter (KF) approach to predict the channel in OFDM symbols with pilot subcarriers where channel affected is by high doppler spread. We design the algorithm considering the lattice-type arrangement of pilot subcarriers in a LTE-Advanced system from 3GPP. In further advancement, we use the filtering of channel impulse response and application of a Wiener Filter for the estimation of the channel frequency response in the rest of the subcarriers.
