Abstract

To avoid significant losses that might be induced by a narrow-band interference (NBI) on the performance of a multi-band (MB) OFDM ultra wideband (UWB) receiver, efficient NBI mitigation schemes are required. This paper proposes a novel mixed-mode NBI suppression scheme that relies on the cooperation between a digital NBI detector and an adaptive analog notch filter. Simulation results show that the proposed mixed-mode suppression scheme improves the performance of the digital frequency excision scheme in a MB-OFDM UWB receiver by as much as an equivalent signal-to-interference ratio gain of 9 dB.
