Abstract

For pilot-aided channel estimation in OFDM systems with a large number of subcarriers, an efficient discrete Fourier transform (DFT)-based interpolator is proposed. To suppress the leakage in a conventional DFT-based interpolator, the proposed method simply reuses the channel frequency response (CFR) estimates at leftmost and rightmost pilot subcarriers.
