Generalized frequency offset estimation in OFDM systems using periodic training symbol

Abstract

For orthogonal frequency division multiplexing (OFDM) systems, the bandwidth is divided into many subcarriers, requiring a highly accurate frequency offset estimator. In this paper, a novel frequency offset estimator utilizing the periodicity embedded in a training symbol is proposed. We generalize the well known correlation-based methods such that the… (More)
