초록

각종 디지털 신규 서비스의 도입으로 인해 발생하는 기존 FWS(Fixed Wireless System) 대역 점유 시스템과 신규 디지털 FWS 간에 발생하는 간섭을 효율적으로 다루기 위해 허용 간섭 기준의 산출이 요구된다. 본 논문에서는 디지털 FWS의 허용 간섭 기준을 산출하기 위한 방법론을 제안하였다. 디지털 FWS의 간섭 유형을 정의하였고, 전송 채널의 특성을 분석하였다. 제안한 방법을 적용하여 다양한 M진 QAM 변조 방식에 따른 허용 간섭 기준을 분석하였다.

The method to determine allowable interference criteria is required due to new digital FWSs(Fixed Wireless Systems) adding to allowable frequency bands, besides current FWSs and digital FWSs. In this paper, we suggested a method to define allowable interference between digital FWSs. Types of interference for FWS were defined and channel characteristics were analyzed. Allowable interference criteria were analyzed using the suggested method for M-ary QAM modulations, which is typical modulation technique of digital FWS.
