In this paper, the authors show the measurement results of Frequency Offset (FO) estimation in Digital Video Broadcasting for Cable version 2 (DVB-C2) receiver which uses Orthogonal Frequency-Division Multiplexing (OFDM). Because FO causes Inter-Carrier Interference (ICI) in a multicarrier system, it should be estimated and compensated to improve the performance of a multicarrier receiver. FO can be divided into Fractional Frequency Offset (FFO) and Integer Frequency Offset (IFO) if FO is normalized to subcarrier spacing.
