Abstract

In this paper, we propose a velocity-adaptive channel estimation scheme using the simple zero-forcing technique in the frequency domain. The proposed scheme is derived by approximating the frequency response of the Wiener filter as the rectangular shape. Channel estimation is performed by removing frequency components that are higher than the maximum Doppler frequency in the received signal. Simulation results show that the proposed scheme outperforms conventional schemes for a wide range of mobile velocities (3 ∼ 300 Km/h).
