Abstract
IV. 연구 결과 본 연구를 통하여, 차세대 IMT-Advanced 시스템의 요구사항에 적합한 단말 RF 트랜시버의 요구사항을 도출하고, 이를 바탕으로 단말 송수신 핵심 구조를 연구, 개발하였다. 광대역(LTE Based 20MHz) OFDM 방식에 적합한 고효율 및 고선형성을 가진 송신 핵심 구조를 개발하여 최대 효율 30%이상을 달성할 수 있음을 입증하였다. 또한, 다중모드와 Scalable BW를 지원하는 디지털 IF 수신기의 핵심 구조를 개발하여 구현 타당성을 검증하고, 핵심 요소 설계 기술을 개발, 완료하였다. 개발된 송수신 구조를 실험적으로 검증하기 위한 성능 시험 플랫폼을 개발하여 송신 신호처리 알고리즘 및 고효율 송신 구조의 성능 시험을 통해 구현 가능성을 분석하였다.
