In this paper we propose a Fast Data Projection Method (FDPM)-based Channel Impulse Response (CIR) estimator of a Decision Directed Channel Estimation (DDCE) scheme for OFDM system. The proposed algorithm is employed in the context of a more realistic channel condition, the Fractionally Spaced (FS)-CIR based channel model. The performance of the proposed algorithm is compared with an earlier proposed deflated Projection Approximation Subspace Tracking (PASTd) algorithm. It is found from the simulation results that the FDPM-based DDCE outperformed the PASTd-based DDCE.
