Abstract

This paper proposes an efficient UWB positioning system using SDS-TWR(Symmetry Double-Sided Two-Way Ranging) and an overhearing technique to estimate the distance and angle of a tag. By allowing auxiliary anchors to overhear SDS-TWR signals, the system eliminates the need for direct packet exchanges or anchor synchronization, significantly reducing complexity and costs. The proposed method supports both synchronous and asynchronous modes, offering flexibility and ease of deployment. Performance evaluations demonstrate high accuracy in distance and angle estimation with minimal communication overhead. Future work will implement the system in real-world environments to validate its performance in applications such as autonomous vehicles, industrial safety, logistics management and smart construction.

이 논문은 SDS-TWR(Symmetry Double-Sided Two-Way Ranging)과 오버히어링(Overhearing) 기술을 사용하여 태그의 거리와 각도를 추정하는 효율적인 UWB 위치 지정 시스템을 제안하며, 보조 앵커가 SDS-TWR 신호를 오버히어링(Overhearing) 할 수 있도록 함으로써 직접 패킷 교환이나 앵커 동기화의 필요성을 없애 복잡성과 비용을 크게 줄일 수 있다. 제안된 방법은 동기 및 비동기 모드를 모두 지원하여 유연성과 배포 용이성을 제공하며, 성능 평가에서는 최소한의 통신 오버헤드로 거리 및 각도 추정에서 높은 정확도를 보여준다. 향후 실제 환경에 시스템을 구현하여 자율 주행차, 산업 안전, 물류 관리 및 스마트 건설과 같은 다양한 응용 분야에서 성능을 검증하고자 한다.
