| Popis: | In this paper, we propose a detection strategy for high rate short-range impulse radio ultra-wideband systems. The proposed detection scheme relies on both the introduction of the cyclic prefix at the transmitter and the use of a frequency domain multiuser detection approach at the receiver. Zero forcing (ZF) and minimum mean square error (MMSE) multiuser detectors have been investigated and compared with the classical RAKE, considering a scenario where several mobile terminals communicate with a base station in an indoor environment characterized by severe multipath propagation. The results show that the MMSE receiver achieves the best performance, irrespective of the number of active terminals. Hence, the proposed detectors appear to be well suited for future indoor wireless applications |
