In this paper, a low-complexity integer frequency offset (IFO) estimation scheme is proposed for an orthogonal frequency division multiplexing (OFDM) based digital radio mondiale plus (DRM+) system. In order to reduce the complexity of the IFO estimation, this paper addresses a grouping of time reference cell (TRC) pilot subcarriers in DRM+ system. The grouping method of TRCs is using the characteristics of phase rotation between TRC subcarriers. The performance of the proposed IFO estimator is compared with the conventional IFO estimator. The simulation results show that the proposed scheme can effectively achieve similar estimation errors in the IFO estimation as well as can be implemented with reduced computational complexity.
