Abstract

The CBS methodology has been utilized in order to make a rapid broadcast of emergency alert based on cellular systems. We present a synchronous cooperative communication method for the CBS. Especially, we suggest a synchronization scheme and a data recovery approach for high-rate cooperative communications. For the high-rate transfer of emergency alert, the cyclic prefix is added to the preamble for the synchronization. For the data recovery, the Alamouti technique is utilized on frequency domain, which is similar to SC-FDE. The simulation results confirm that our proposed scheme is very suitable for the CBS.

이동통신망을 이용한 재난경보의 신속한 방송을 위해 CBS 기능이 이용된다. 본 논문에서는 이 CBS 기능을 위한 동기식 협력통신 방식을 제안한다. 특히 고속 전송을 위한 동기 방식과 데이터 복구 기법을 제안한다. 고속 전송 환경에서의 동기를 위해 주기 전치부가 있는 프리엠블이 이용되며 데이터 복구를 위해 SC-FDE와 유사한 주파수 영역에서의 Alamouti 기법을 이용한다. 모의실험 결과는 제안된 방식이 CBS에 매우 적합함을 보여준다.
