Deterministic Channel Models for Wireless Communications

  • Published : 2007.09.30

Abstract

최근 컴퓨터 발전에 따라 이동통신용 채널모델로 deterministic방법이 활발히 연구되고 있다. 이 방법은 기존의 stochastic방법과 달리 주어진 환경의 전파전파현상을 물리 이론을 바탕으로 정확하게 예측하는 것을 목적으로 한다. 그러므로 차세대 주파수 환경 분석과 같은 다양하고 새로운 분야에 적용가능하고 연구의 진전에 따라 모델의 정확도 및 신뢰도가 점점 높아지고 있다. 그러므로 본보에서는 현재까지의 연구 결과를 정리하고 방법의 장단점을 논한다.
