초록

무선 이동통신 환경에서 몇 가지 까닭으로 말미암아 신호의 도래각이 통계적으로 퍼지게 될 때, 점신호원 모형대신 이러한 환경에 적합한 새로운 모형이 필요하다. 이 논문에서는 새로운 각 퍼짐 신호원 모형을 제안하고, 그 모형 아래에서 고유값 분해기법에 기초한 신호 도래각 추정방법을 제안할 것이다. 추정 에러의 근사적인 분포는 통계적 특성을 통해 알 수 있다.

If the angle of arrival (AOA) of a source is perturbed due to some reasons in a statistical way as in the environment of wireless mobile communications, a new model appropriate for such environment should be used instead of the point source model. In this paper, an angel-perturbed source model is proposed and an estimation method based on the eigen-decomposition tecklique is investigated under the model. The asymptotic distribution of the estimation errors is obtained to observe the statistical properties.
