Abstract

A frequency offset estimation scheme is proposed for orthogonal frequency division multiplexing (OFDM) systems. In the conventional scheme, there is a disadvantage that the performance is sensitive to the fractional frequency offset variation. Thus, a novel scheme is employed to estimate the frequency offset. The proposed scheme is robust to the fractional frequency offset variation and the performance is better than the conventional scheme.
