시간 영역에서 정밀한 레인징을 수행하는 동안 고려해야 할 가장 중요한 사실은 송신기의 첫 번째 도착에 해당하는 시간을 어떻게 정확하게 추정할 것인가이다. 그러나 상관관계 저하로 인해 단순 상관기 사용으로는 TOA(Time-of-arrival) 추정치를 추출하기 어려우며, 펄스 반복 간격(PRI)이 최대 초과 지연보다 작은 경우 (MED). 상관 능력을 향상시키기 위해 본 논문에서는 다중 마스크 연산(MMO)을 사용하는 비일관성 시스템에서 미리 정해진 임계값을 따르는 TOA 추정 방법을 제안한다. 제안된 기법의 성능은 두 가지 채널 상황에서 시뮬레이션을 수행하여 검증된다. 시뮬레이션 결과는 제안한 방식이 밀집된 실내 다중 경로 환경과 여러 SOP(동시 작동 피코넷)가 존재하는 경우에도 잘 작동함을 보여줍니다.

Abstract: During the execution of precise ranging in the time domain, the most important fact to consider is how to achieve an accurate estimate of the time corresponding to first arrival of the transmitter. However, it is difficult to extract an estimate of the time-of-arrival (TOA) through use of a simple correlator due to degradation on correlation, and in the case where the pulse repetition interval (PRI) is less than the maximum excess delay (MED). In order to enhance the correlation capability, this paper proposes a TOA estimation method that obeys a threshold predetermined in a non-coherent system using multiple-mask operation (MMO). The performance of the proposed scheme is verified by conducting simulations under two different types of channel situations. The simulation results show that the proposed scheme performs well even in a dense indoor multipath environment and with the existence of multiple simultaneously operating piconets (SOPs).
