Integer Frequency Offset Synchronization Scheme With Low Implementation Complexity for OFDM Systems

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.
