In orthogonal frequency division multiplexing system (OFDM), rapid channel variation caused by fast moving receiver leads to a loss of subcarrier orthogonality which results in inter-carrier interference (ICI) and receiver performance degradation. In conventional receivers, performance is enhanced by estimating ICI and removing it from received signals. In this paper, an ICI reduction scheme using a time-domain mask and adding is proposed. The proposed scheme is applied to DVB-T receiver to
