Abstract

본 발명은 디지탈 코드분할 다원접속 셀룰라 서비스 제공시, 터널, 빌딩내, 지하공간 등 전파음영지역 및 도로, 산간지역 등 원격지에 대해 대역확산 셀룰라 서비스를 제공하기 위해 양방향 신호에 시간지연을 주는 방식을 채용한 중계방송방법에 관한 것으로, 종래의 중계기에 전력분배기, 전력결합기, 지연소자와 이동국 방향으로의 안테나를 추가하여 다중경로를 제공하고 순방향 링크에 다이버시티 효과를 줌으로써, 코드분할 다원접속 셀룰라 시스템에서 기지국 통화용량에 영향을 주지 않고 짧은 다중경로 페이딩 환경에 디지탈 코드분할 셀룰라 서비스 제공이 가능토록 하며, 개방지역에서 흔히 발생되는 기지국 송신신호와 중계기 송신신호간 간섭을 완화하여 중계기 설치 및 무선망설계를 용이하게 하는 디지탈 코드분할 다원접속 셀룰라용 중계방법이다.The present invention provides a method for giving a time delay to a bidirectional signal to provide a spread spectrum cellular service for radio coded shade areas such as tunnels, buildings, underground spaces, and remote areas such as roads and mountain areas when providing digital code division multiple access cellular service. The present invention relates to a relay broadcasting method employing a code division multiple access cellular system by providing a multi-path by adding a power divider, a power combiner, a delay element and an antenna toward a mobile station in a conventional repeater, and giving a diversity effect on a forward link. It is possible to provide digital code division cellular service in a short multipath fading environment without affecting the base station call capacity, and to alleviate the interference between the base station transmission signal and the repeater transmission signal which are common in the open area, repeater installation and wireless network design For digital code division multiple access cellular to facilitate It is a method of system.
