IEEE Transactions on Consumer Electronics, 2008•ieeexplore.ieee.orgThe main disadvantage of orthogonal frequency division multiplexing (OFDM) systems is its
sensitivity to carrier frequency offset and timing offset. This paper proposes a simple way of
improving the performance of a residual frequency offset (RFO) estimator in OFDM-based
digital video broadcasting (DVB) system. To demonstrate the efficiency of the proposed RFO
estimator, comparisons are made with conventional estimator in terms of mean square error
(MSE) performance, estimation range, and complexity.
