Abstract
차세대 지상파 방송 규격인 Advanced Television Systems Committee (ATSC) 3.0 에서는 OFDM 심볼내의 특정 부반송파 대역에서 발생하는 군집 오류(burst errors)로 인한 성능 열화를 극복하기 위하여 주파수 인터리버 (frequency interleaver) 기법을 채택하였다. 주파수 인터리버는 OFDM 심볼 내의 데이터의 위치를 랜덤하게 배열하여 채널에서 발생하는 군집 오류 (burst error)를 분산시켜 성능 열화를 극복한다. 본 논문에서는 다양한 채널 환경에서의 주파수 인터리버의 성능을 펑가하고 효과를 분석한다.
