초록

본 논문에서는 다중경로 채널 조건과 부반송파 변조방식이 다른 OFDM에 대한 성능을 분석한다. 또한 OFDM 신호에 대한 다중경로 지연 확산 환경, 시작 프레임 동기 오류의 영향에 대해서 분석한다. 다른 변조방식에 대한 BER 성능 분석을 통해서 적응형 OFDM 전송에 적용할 수 있는 기준을 제시한다.

We analyze an analysis of the performance of OFDM(Orthogonal Frequency Division Multiplexing) under multipath channel conditions, and to allow for different OFDM configurations. In this paper, the effects on multipath delay spread, peak power dipping, channel noise and time synchronization errors for the OFDM Signals are analyzed.
