Abstract:
Chirp Spread Spectrum (CSS) defined in IEEE 802.15.4a, known to be resistant to signal interference and multipath fading, can perform precise ranging and it is a promising technology for localization systems. This paper is designed to investigate the performance and characteristic of CSS ranging in LOS and NLOS surroundings. On the basis of the experimental analysis, we propose a voting-averaging filter to deal with the problem of unpredictable abnormal ranging points and measurement noise. Secondly, we further propose a uniform model of CSS ranging, which can apply to LOS and NLOS range measurement, to improve the performance of distance measurement.
