초록

본 논문은 광무선 (fiber-radio)링크를 통한 OFDM(orthogonal frequency division multiplexing) 신호 전송 시스템의 성능을 분석한다. 전체 시스템에 대한 기저대역 등가 모델을 유도했으며 광링크 상에서의 혼변조왜곡(IMD : intermodulation distortion) 전력과 OFDM 신호의 부반송파 개수 사이의 상관 관계를 증명하였다. 이를 이용해서 전체 시스템의 CNR을 유도하였으며 각 변복조 방식의 요구되는 CNR 관점에서 OFDM 신호의 최대 부반송파 개수를 시뮬레이션에 의해 추출하였고 여러 시스템 파라메타와 CNR과의 관계를 조사하였다.

This paper presents the analysis of fiber radio system transmitting OFDM signal. We propose a baseband equivalent system model and prove the relation between the IMD(intermodulation distortion) power and the number of subcarrier in the OFDM signal. Using this relation, we derive the CNH of the overall system. In terms of the required CNR for each digital modulation scheme, we extract the maximum number of the subcarrier in the OFDM signal using simulation and examine how the system parameters are related with the CNR.
