The Sensitivity of a Flexible Form of MC-CDMA to Synchronisation Errors

In this contribution, we propose a variant of the MC-CDMA system that offers more flexibility than the traditional MC-CDMA system. We investigate the sensitivity of this flexible MC-CDMA system to some types of synchronisation errors. This flexible MC-CDMA system is not affected by a constant phase offset or a constant timing offset, as in the proposed flexible MC-CDMA system the carriers inside the rolloff area are not used. Furthermore, the flexible MC-CDMA system is very sensitive to a carrier frequency offset or a clock frequency offset, while the system is less sensitive to carrier phase jitter or timing jitter.
