CDMA Multiuser Detection Using Unscented Particle Filtering
Rui Hou, Santong Zhang, Gang Zhu · 2007
In this paper, unscented particle filtering (UPF) is applied to multiuser detection (MUD) in synchronous code division multiple access (CDMA) environments. The UPF algorithm consists of a particle filtering (PF) that uses an unscented Kalman filtering (UKF) to generate the importance proposal distributions, which match the true posterior better. The simulation results show that the UPF-based multiuser detector almost always outperforms the PF-based one both in the equal power situation and the near-far case.
