Abstract

In this contribution we investigate the robustness of mixed impulse radio and UWB-OFDM systems under impulsive noise being typical in UWB multiuser environments. We propose a new receiver structure suppressing iteratively the impulsive noise without use of an adaptive clipper. Hence, the delicate problem of tracking a (sub)optimal threshold is avoided. The performance of this structure in comparison with a conventional UWB-OFDM receiver is illustrated.
