Abstract

In this paper, a residual frequency offset (RFO) estimator is proposed for ultra-wideband multi-band orthogonal frequency division multiplexing (UWB MBOFDM) systems. The proposed scheme uses a frequencydomain spreaded data samples which is provided in MBOFDM system. To demonstrate the efficiency of the proposed RFO estimator, comparisons are made with other existing estimators.
