In this paper we consider the uplink transmission within a DS-CDMA system employing CP-assisted (Cyclic Prefix) block transmission techniques combined with spatial multiplexing techniques that require multiple antennas at both the transmitter and the receiver. We present an efficient frequency-domain receiver structure with iterative MUD (Multiuser Detection). The performance of the proposed receiver can be close to the single-user matched filter bound, even for fully loaded systems and/or severely time-dispersive channels.
