Abstract

The performance of synchronous multi-user detectors in wireless CDMA fading multipath channels, such as indoor channels for personal communications is investigated using eigen analysis via the Karhunen-Loeve transformation (KLT). A modified receiver design is introduced to eliminate the multiple-access interference (MAI) between the different users in the two cases of a single receiving antenna and multiple receiving antennas (space diversity)
