Abstract

Ultra-wideband (UWB) ranging poses a set of time delay estimation problems for designers. The possibility of a large error can be a challenging problem for accurate ranging and positioning. An approximate analysis of large error performance of UWB ranging in multipath and multiuser environments is posed. Both analytical and experimental approaches are taken to evaluate the large error variance in a correlation-based serial search scenario.

초광대역 신호의 높은 시간해상도는 복잡한 다중경로 환경에서의 정밀한 거리추정 및 위치추적 을 가능하게 한다. 그러나 신호의 도착신호 추정시 발생하는 큰 추정오차의 발생은 거리추정의 정확도를 저하시키는 요인이 된다. 본 논문에서는 다중경로, 다중사용자 환경에서 초광대역 거리추정의 성능을 평가한다. 상호상관을 이용한 직렬검색 알고리듬을 적용할 때 발생하는 추정오차를 분석하고 모의실험 결과를 개시한다.
