Summary:
In this letter, a pilot-less sampling frequency offset estimation scheme is presented for ultra-wideband orthogonal frequency division multiplexing (UWB-OFDM) systems. This scheme is based on the fact that two consecutive symbols convey the same information in the UWB-OFDM system, thus removing the need of pilot symbols. The performance of mean square error has been evaluated through simulation to verify the usefulness of the proposed scheme.
