Abstract

This paper concerns the design of a matching module system enabling the RF signal to be harmonized between the new base stations (RRH) and the repeater in the same frequency band of the asynchronous transfer network. This matching system controls the RF Gain Control of the module while monitoring the quality of the quality. Additionally, the RF environment has been adapted accordingly to adjust the RF Gain Control to match the receiver characteristics of the relay. As a result of this study, we improved the quality of the interface between the new base stations and existing relays.

본 논문에서는 비동기식 이동통신망의 동일 주파수 대역에서 신형 원격 기지국(RRH)과 중계기간에 RF 신호가 상호 정합이 가능하도록 하는 정합 모듈 시스템 설계에 관한 것이다. 이 정합 시스템은 통신 중에 있는 모듈의 RF Gain을 제어하고 품질상태를 모니터링 한다. 또한 Network의 RF 환경변화에 따라 RF Gain을 적절히 조절하여 중계기의 수신 특성에 맞게 정합 할 수 있는 기능을 부여하였다. 본 연구의 결과로 신형 기지국과 기존 중계기간에 상호 인터페이스 품질문제를 개선하였다.
