Narrowband interference migration is of specific importance in delay hopped transmitted reference ultra wideband (DHTR-UWB) communication systems. In this paper, we propose a novel algorithm for narrowband interference mitigation in aforementioned systems. The method is based on eigen analysis of the signal-plus-noise-plus-interference subspace. To this end, we first outline a complete system and...
Transmitted-reference ultra-wideband (TR-UWB) systems, in conjunction with autocorrelation-receivers (AcR), can collect all energy of the multipath channel response at low complexity. Unfortunately the AcR front-end also collects the energy of narrowband interference (NBI) signals, which severely degrades its performance. We present an elaborate statistical analysis of the NBI for a multichannel AcR...
