An Iterative FrequencyDomain Decision-Feedback Receiver for MC-CDMA Schemes

Coded Division Multiple Access) combine a CDMA scheme with an OFDM modulation (Orthogonal Frequency Divi-sion Multiplexing), so as to allow high transmission rates over severely time-dispersive channels without the need of a complex receiver implementation. In this paper we propose an iterative frequency-domain decision-feedback receiver for MC-CDMA signals. The proposed receiver has excellent performance, close to the single-code MFB (Matched Filter Bound), even for severe time-dispersive scenarios and/or in the presence of strong interfering channels
