Abstract

In this paper, we suggested new additional data transmission technology for T-DMB system using MOK-SS(Mary Orthogonal Keying- Spread Spectrum)mapping method. We applied revised watermarking method of TxID(Transmitter Identification) technology mainly had been used for conventional ATSC-DTV(Advanced Television Systems Committee - Digital TV). And proposed schemes enhanced additional data rate using MOK-SS mapping method. We certified availability of our proposed technology by using various simulation and error rate performance analysis.

본 논문에서는 지상파DMB(T-DMB)전송신호에 고효율로 부가적인 데이터의 전송을 가능하게 하는 기술로서 MOK-SS(Mary Orthogonal Keying- Spread Spectrum)매핑 기반의 T-DMB 부가데이터 전송기법을 새롭게 제안하였다. 본 논문에서는 T-DMB에 기존의 ATSC(Advanced Television Systems Committee)방식 디지털 TV에서 다루던 송신기 식별기술(TxID;Transmitter Identification)용 워터마킹기법을 T-DMB에 적용함과 동시에 MOK-SS매핑기술까지 활용하여 부가적인 데이터 전송율을 획기적으로 증가시켰다. 본 논문에서는 제안한 기술에 대하여 몇가지 사례에 대한 모의실험 및 성능분석을 통하여 제안기술의 유용성을 확인하였다.
