Abstract :
Recently, multiband OFDM (MB-OFDM) ultra wideband (UWB) communication system is actively investigated for high speed wireless communication system. In this system, frequency hopping (FH) and OFDM are implemented for high data-rate transmission, but this combination of FH and OFDM makes frequency offset as a considerable problem. In this paper, a novel frequency offset compensation scheme by symbol mapping at frequency spreading for MB-OFDM is proposed, and its performance is evaluated through the computer simulation.
