Abstract
Time-hopping impulse radio (TH-IR) systems are very attractive in providing high data rates in multiple access communication channels. By taking advantage of the special signal structure of this kind of systems, one can design an effective multiuser detector. In this paper an iterative multiuser detection (MUD) algorithm is developed for TH-IR systems. The developed MUD algorithm consists of two stages and follows the turbo principle. The novelty of the developed algorithm is that the potential exponential complexity is avoided. Simulation results show that the developed MUD algorithm can achieve satisfactory performances with significantly reduced computational complexity.
