Ultra Wideband (UWB) Interference on UMTS Receivers

Abstract

This paper discusses the effects of impulse radio ultra wideband (UWB) interference on narrowband radio systems. It presents the fundamental mathematical modeling of the interaction between the UWB signal and the narrowband victim receiver. Further, as an example, it demonstrates the effects of UWB interference on a UMTS receiver through simulations, showing how the receiver response varies as the pulse repetition frequency (PRF) of the UWB signal varies. We show that depending on the pulse rate, signal dithering and receiver demodulation bandwidth, UWB interference can be modeled as additive white Gaussian noise (AWGN)
