N2 - This paper presents a low-complexity interpolation-based channel estimator suited for scattered-pilot OFDM systems in fast-fading channel. The proposed estimator consists of two interpolators: one RLS interpolator for estimating scattered subcarriers along the time direction and another raised-cosine (RC) interpolator for estimating data subcarriers along the frequency direction. A low-complexity architecture tailored for DVB-T/H is demonstrated as an exemplar. Simulation results show that the proposed channel estimator has comparable accuracy with almost order-of-magnitude lower complexity than conventional adaptive channel estimators.
