초록

초광대역 무선 통신에서 불규칙 각도 퍼짐이 발생하는 초광대역 옥내 환경에 적합한 새로운 신호 모형을 제안하고 군집된 초광대역 신호의 도착 방향(AOA)을 추정한다. 제안된 모형에 적합한 부공간 추정기법을 적용하여 수신된 초광대역 군집 신호의 신호 도착 방향과 퍼짐모수의 추정치를 얻는다. 제안된 모형과 추정기법은 컴퓨터 모의실험으로 검증되며 추정 오차의 성능도 분석한다.

In this study, a new signal model suitable for UWB indoor environments with random angle spread is proposed to estimate the angle-of-arrivals(AOAs) of UWB cluster signals in an UWB wireless communication. A subspace based estimation technique adopted for this model is investigated and the estimates of the AOA and distribution parameter on the received UWB cluster signals are obtained. The proposed model and estimation technique are verified using computer simulations, and the performance of the estimation error is analyzed.
