초록

본 논문에서는 무선 및 이동통신을 위한 클라우드 무선 가입자 네트워크를 지원하는 프론트홀에서 무선 라디오파의 광섬유 전송망의 기술을 제안하고 구현한다. 하향 링크는 OFMD (orthogonal frequency division multiplexing) (O기법을 사용하였고 상향방향의 전송은 SC-FDMA (single carrier-frequency multiple access) 방식으로 구현하였다. 64, QAM, 16QAM, QPSK 등 다양한 변조 방식에 대해 시스템 파라메터를 도출하고 측정치를 기반으로 성능을 분석하였다.
