Abstract :
In this letter, a fine carrier frequency offset (CFO) estimator is proposed for ultra-wideband multiband orthogonal frequency division multiplexing (UWB MB-OFDM) systems. The proposed scheme uses a frequency-domain spreaded data symbol which is provided in the MB-OFDM system, thus removing the need of training symbols. Analytical expression of the mean square error (MSE) of the fine frequency synchronization scheme is reported, and simulation results are used to verify the theoretical analysis developed in this letter.
