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.
RT (ray tracing) tools are commonly used to simulate UWB-IR (ultra wideband-impulse radio) propagation channel for different applications like network optimization, interference monitoring, or localization based applications. In this paper, different methods of reconstructing received signal in RT tools are presented, concluding that they are not all equivalent from digital implementation point of...
In this paper, we present an algorithm that interprets the specificities of the received direct path, depending on the particular deformations due to antennas, in the context of Impulse Radio - Ultra Wide Band (IR-UWB) peer-to-peer communications. The goal is to jointly estimate direct path Direction of Arrival (DoA) and Direction of Departure (DoD). The proposed technique is mainly based on prior...
