MC-CDMA systems are promising candidates for new generation mobile access systems. In MC-CDMA systems, wide bandwidth is divided into narrow-band sub-carriers. Therefore, precise compensation of frequency offset is important. And, in new generation mobile access systems, we have to consider large frequency offset because the use of micro wave band is expected. By considering them, in this paper, we propose novel frequency synchronization method with guard interval and pilot symbol that realizes accurate synchronization and have large compensation range. We clarify the effects by computer simulation.
