Abstract
AbstractIn this contribution, we investigate the sensitivity of MC‐CDMA systems to synchronisation errors. We show that the signal‐to‐noise ratio (SNR) of the MC‐CDMA system at the input of the decision device in the presence of a carrier frequency offset or a clock frequency offset is a rapidly decreasing function of the number of carriers. For a maximal load, carrier phase jitter and timing jitter give rise to a degradation that is independent of the spectral content of the jitter; moreover, the degradation caused by carrier phase jitter is independent of the number of carriers. A constant carrier phase offset and a constant timing offset cause no degradation of the MC‐CDMA system performance.
