Signal Processing for UWB

The presented work addresses a comparison between measured and simulated data in an Indoor On-body channel for motion capture scenario. Measured data used in this work come from a large dataset of BAN channel open data, shared by the NICTA laboratory. The simulated data are produced using the PyLayers physical simulation platform based on graph based ray tracing techniques.

This paper regards the application of ray tracing (RT) tools for indoor localization techniques. The paper presents two possible applications of RT tools in that context. The first is the train/construction of fingerprints databases in order to complement or/and replace laborious measurement campaigns. The second application is the modeling of location-dependent parameters in order to feed localization techniques. These two applications are investigated and validated using three RT tools applied on a synthetic indoor environment. The obtained results showed that RT tools are reliable in both fingerprinting databases construction and LDPs modeling.

Este artículo realiza una revisión del estado del arte de la tecnología basada en canales de Banda Ultra Ancha (UWB, Ultra–Wideband) enfocándose en su regulación, estandarización, aplicaciones básicas, modelo de canal IEEE 802.15.4a y simulación de la respuesta impulsiva de este tipo de canal. También se pretende introducir al lector en las tecnologías basadas en canales IR–UWB y en los parámetros para el modelamiento y simulación del canal UWB IEEE 802.15.4a.

This paper presents a 3D-RT simulator which allows indoor radio wave propagation modeling for multi-standard systems, including UWB. It focuses on the issue of simulation of deterministic radio channel with realistic antenna behavior. Vector Spherical Harmonics (VSH) expansion of antenna radiation vector function is used to have efficient data access, good compression factor, and fast waveform reconstruction.
