Abstract:

In this paper, a fine carrier frequency offset synchronizer is presented for ultra-wideband multi-band orthogonal frequency division multiplexing (UWB MB-OFDM) systems. The proposed scheme uses a channel estimation (CE) sequence provided in the current UWB MB-OFDM system and is designed to be insensitive to a sampling clock frequency offset. To demonstrate the efficiency of the proposed fine frequency synchronizer, comparisons are made with the conventional frequency synchronizer in terms of mean square error.
