Improving the performance of a radio-frequency localization system in adverse outdoor applications

Abstract: In outdoor RF localization systems, particularly where line of sight can not be guaranteed or where multipath effects are severe, information about the terrain may improve the position estimate’s performance. Given the difficulties in obtaining real data, a ray-tracing fingerprint is a viable option. Nevertheless, although presenting good simulation results, the performance of systems trained with simulated features only suffer degradation when employed to process real-life data. This work intends to improve t… Show more

“…Signal strength is also heavily dependent on the propagation environment. Attenuation caused by fading, multipath, and other RF impairments injects large amounts of noise into the RSS measurements [22] and influence the SNR of the signal. The path loss of an RF signal describes the attenuation caused by the distance the signal travels in addition to the previously mentioned impairment effects.…”
