In this paper, we consider a reduced-rank adaptive channel estimation for Orthogonal Frequency Division Multiplex ing (OFDM) systems. The pilot-aided channel estimation is rawly carried out in the time domain, which is shown to have the better performance compared to the frequency domain estimator. The adaptive modified Least Mean Square (LMS) algorithm is then applied to further improve the es timates of the channel coefficients. In order to attain lower complexity as well as fast convergence, a reduced-rank tech nique is also applied to the adaptive algorithm.
