Abstract

We consider a space-time iterative multiuser (STIM) receiver for a flat fading channel and examine its application in a DS-CDMA mobile communication system with forward error correction (FEC) coding. This multiuser receiver structure exploits its spatial and temporal capabilities to overcome interference. Numerical results shows that a significant increase in capacity over flat fading channels is achieved by combining efficient space-time coding (STC), multiuser detection (MUD), iterative signal processing techniques and the reuse of orthogonal spreading codes.
