Iterative multiuser detection for space-time coded ultra-wideband systems

Abstract

This paper proposes a low-complexity iterative multiuser detection (MUD) algorithm for synchronous ultra-wideband systems with analog space-time coding. We use the maximum a posteriori criterion in the detection process and reduce the computational complexity in an iterative manner. The simulation results demonstrate that this iterative MUD scheme has a BER performance approaching to that of the single-user system.
