초록

본 논문에서는 지상파 클라우드 방송 시스템 (cloud transmission system)을 위한 수신기 초기 타이밍 획득 알고리즘을 제안한다. 제안된 방식은 프리앰블 심벌 내의 다양한 반복패턴에 대한 자기상관 값들을 결합하여 동일채널간섭이 존재하는 클라우드 방송 시스템에서 타이밍 메트릭의 신뢰성을 향상시킬 수 있다. 전산 실험 결과는 제안한 방식이 클라우드 방송 시스템 환경에서 타이밍 메트릭의 신뢰성을 향상시킴을 보여준다.

In this paper, we propose an initial timing acquisition algorithm for terrestrial cloud transmission (CTxn) systems. By combining auto-correlations of several repetition patterns within preamble symbols, the proposed scheme can improve the reliability of the timing metric for CTxn system with co-channel interferences. Simulation results show that the proposed scheme improves the reliability of the timing metric for terrestrial CTxn systems.
