摘要

在这篇贡献中，我们研究了混合脉冲无线电和UWB- ofdm系统在UWB多用户环境中典型的脉冲噪声下的鲁棒性。提出了一种不使用自适应滤波器的迭代抑制脉冲噪声的新型接收机结构。因此，避免了跟踪(次)最优阈值的棘手问题。通过与传统UWB-OFDM接收机的比较，说明了该结构的性能。

Iterative impulsive noise suppression in mixed impulse radio and UWB-OFDM systems

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.
