Abstract
ATSC 방식의 지상파 디지털 TV 방송에서는 단일 주파수 망(Single Frequency Network: SFN) 구성 시 단일 주파수 사용에 따른 인접 송신기 혹은 중계기에 대한 간섭 문제가 발생한다. 이를 해결하기 위해 ATSC 권고에서는 각 송신기 및 중계기에 식별(Transmitter Identification: TxID) 신호를 할당하여 송신 및 중계 신호에 부가하여 전송하고, TxID 신호분석기를 통하여 각 송신기 및 중계기에 의해 발생되는 채널환경을 검출하여 망을 제어한다. 본 논문에서는 TxID 신호로 사용되는 Kasami 수열의 생성 및 DTV 신호로의 삽입방법에 관해 살펴보고, TxID 신호의 효율적인 분석을 위한 TxID 신호분석기의 구조를 제안한다. 또한, 수학적인 분석을 통해 제안된 TxID 신호분석기의 성능을 고찰하고, 전산실험 및 실험실 테스트를 통해 제안된 TxID 신호분석기의 성능을 검증한다.
