Abstract
A robust interference canceller for Multi-Carrier Code Division Multiple Access (MC-CDMA) using Orthogonal Frequency Division Multiplexing (OFDM) in Rayleigh fading is proposed. This interference canceller is robust in the sense that it cancels Inter-Carriers Interference (ICI) and is suitable for use in dispersive channels. To come up the effects of the signal dispersion, Doppler shifts and delay spreads on the performance of MC-CDMA systems over mobile fading channels, this interference canceller exploits the merit of the orthogonal signaling and pilot signals to evaluate the channel parameters. This interface canceller is well suited to work in iterative turbo interference cancellation.
