Abstract
Ultra-wideband (UWB) has been increasingly integrated into devices such as smartphones and digital keys, where it is expected to be used not only for data transmission but also for high-precision ranging. In particular, the IEEE 802.15.6ma standard for Body Area Network (BAN) considers mutual communication via UWB transmission between Human BAN (HBAN), which are attached to the human body, and Vehicle BAN (VBAN), which are installed in vehicles such as buses. However, as UWB-enabled devices become more widespread, mutual interference among UWB signals may degrade ranging accuracy, highlighting the need for a quantitative evaluation of ranging performance under interference conditions. In this study, we evaluated the ranging accuracy of UWB systems in environments where multiple BANs coexist, using computer simulations that model multipath conditions in a hospital room. Furthermore, to mitigate the effects of interference, we proposed a UWB ranging method that employs M-sequence spreading codes, and verified its effectiveness. Simulation results demonstrate that the use of M-sequences improves ranging accuracy under interference-rich conditions.
