Abstract

In this paper we will show that the impact of narrowband interference signal on the performance of direct sequence ultra wide band communication system in a Log-normal flat fading channel can be easily mitigated. The idea of the proposed mitigation technique is based on adapting the ultra wideband transmitted spectrum with the suitable selection of the direct sequence pseudo random code sequence in order to counteract narrowband interference and at the same time to guarantee low spectral emissions over existing narrowband communication systems.
