Timed simulator for UWB communication systems

Abstract

The UWB field gathers a wide range of research directions. The numerous pulsed system principles that have been proposed in the literature differ by pulse nature (e.g. monocycle, chirp), by modulation type (e.g. BPSK. PPM with time hopping, chaotic PPM, multi-carrier), or by system architecture (e.g. analog correlation, tunnel diode detection). In parallel with in-depth theoretical studies, the need for a versatile simulation tool is strong. The goal of the simulator presented in this paper is to provide a comprehensive, fully parametric simulator for UWB communication systems research and development. The focus has been primarily put on a point-to-point transmission link, which will be exported to more general network simulators. Results on UWB direct sampling are also presented for line-of-sight and Saleh-Vatenzuela channel models.
