Abstract

The performance of a multi-carrier code division multiple access (MC-CDMA) system in the downlink is studied over HIPERLAN2 channels representative of indoor environment. Performance results of MC-CDMA systems are presented for different single user (SU) and multi-user (MU) equalization techniques. The influence of channel coding and frequency interleaving is evaluated for both systems. For MU detectors, channel decoding has been also used in order to improve MAI cancellation in the iterative process. Simulations results are presented
