Abstract

셀룰러 전화기의 위치를 결정하는 분야는 정확도에 영향을 끼치는 고층 다중 경로의 도시환경으로 인해 어려움을 겪는다.The field of determining the location of cellular telephones suffers from the high multi-path urban environment which affects accuracy.

이 문제는 두개 단계가 종합된 접근법, 즉 셀룰러 기지국에 배치된 시스템(10)을 이용하는 개략 위치 결정 단계와 고층의 다중경로 환경에서 가능할 수 있는 휴대용 수신기(26)를 이용하는 후속의 정밀 위치 결정 단계를 포함하는 접극법에 의해서 극복될 수 있다. 응용예에는 긴급 호출과 범죄수사분야를 포함한다.This problem involves a two-step combined approach: a coarse positioning step using a system 10 deployed at a cellular base station and a subsequent precise positioning step using a portable receiver 26, which may be possible in a high-rise multipath environment. It can be overcome by the included polarization method. Applications include emergency calls and criminal investigations.
