Abstract

We have designed and implemented a receiver of Eureka-147 Digital Audio Broadcasting (DAB) scheme. DAB used OFDM (orthogonal frequency division multiplexing) as its transmission technique that is very sensitive to synchronization error. So reliable synchronization algorithms have been proposed and evaluated. With the algorithms we proposed a PC based real-time DAB receiver has been implemented. We find that the receiver performs satisfactorily to meet the specifications we determined.

본 논문은 Eureka-147방식의 DAB수신기의 구현 및 동기 알고리즘을 다룬다. 이를 위해 수신기의 성능 및 규격을 결정하고 이를 만족하는 수신기 설계에 대하여 살펴본다. 특히 DAB는 OFDM(orthogonal frequency division multiplexing)을 전송방식으로 사용하여 동기성능이 전체 수신성능에 큰 영향을 미친다. 따라서 본 논문에서는 수신기에 적용될 신뢰도 높은 동기알고리즘을 제안한다. 설계된 DAB수신알고리즘을 바탕으로 PC기반의 실시간 수신기가 구현되었고 구현된 수신기는 요구되는 동기오차 및 비트오류율을 만족함을 확인하였다.
