Performance of relay-aided downlink DS-CDMA system using transmitter preprocessing based on feedback information

- Performance of relay-aided MUTP-assisted DL DS-CDMA is investigated for the following cases.
- MUTP based on perfect CIRs.
- MUTP based on ideal feedback of VQ-CIRs.
- MUTP based on noisy feedback of VQ-CIRs.
- MUTP based on noisy and fading feedback of VQ-CIRs.
