The 3rd generation cellular mobile and wireless personal communication systems are expected to accommodate not only high quality voice services, but also a broad range of other multi-rate services. Of the various access protocols, wideband Code-Division Multiple-Access (CDMA) has emerged as the key air interface because of its high frequency utilization and suitability for handling multimedia and multi-rate services. In this paper, we propose a simple, robust and effective objective function based Multi-user detection (MUD) receiver. Numerical results over the AWGN and fading channels will show that significant capacity and performance improvement can be achieved compared with the conventional DS/CDMA receiver.
