    Abstract

    In this paper, the impact of the noise due to undersampling of noncoherent narrowband interference in time domain UWB channel measurements is investigated. Different measurements were carried out within the building for LOS and NLOS situations. The obtained results show that energy of external narrowband interference (especially at frequencies below 3.1 GHz) is spread over the whole measured bandwidth (1-12 GHz) as a quasi-white noise. This spreading is caused by the stroboscopic sampling receiver and used in the measurement setup. The leel of this additional noise is relatively high and its suppression is required for long-distance by an analogue bandpass filter directly after the receive antenna substantially decreases the noise floor and results in a large improvement of the singal-to-noise ratio.
