A novel approach to in-band interference mitigation in ultra wideband radio systems

Abstract

Ultra wideband (UWB) radio transmission is a very important topic and, at present, a lot of work is devoted to increasing the use of this technology. In this regard, a crucial point is to evaluate performance loss induced by the in-band interference generated by concurrent services ("foreign services") to try to limit it. We present a novel algorithm to estimate and suppress an external interference in UWB systems so as to increase the SIR (signal-to-interference ratio) and thus to achieve performance near to that of interference-free UWB systems.
