모바일 네트워크를 통한 멀티미디어 통신은 변동적인 채널 저하로 인해 어려움을 겪습니다. 기존의 오류 처리 방식은 무선 인터페이스의 첫 번째 단계 오류 정정 디코딩과 멀티미디어 디멀티플렉서의 두 번째 단계 오류 정정 디코딩으로 구성되며, 여기서 두 번째 단계의 디코딩 결과는 첫 번째 단계의 디코딩 성능을 향상시키는 데 사용되지 않습니다. 보다 강력한 오류 보호 요구 사항을 충족하기 위해 멀티미디어 디멀티플렉서의 오류 정정 디코딩에 의해 생성된 우도 출력이 무선 인터페이스의 디코딩으로 피드백되는 멀티미디어 통신에서 반복적인 소프트 입력/소프트 출력 오류 정정 디코딩을 제안합니다. 디코딩 절차가 반복됩니다. 성능은 모바일 채널을 통한 MPEG-4 비디오 전송 시뮬레이션을 통해 평가되었습니다.

Abstract: Multimedia communications over mobile networks suffer from fluctuating channel degradation. Conventional error handling schemes consist of the first stage error correction decoding in wireless interface and the second stage error correction decoding in multimedia demultiplexer, where the second stage decoding result is not used to improve the first stage decoding performance. To meet the requirements of more powerful error protection, we propose iterative soft-input/soft-output error correction decoding in multimedia communications, where the likelihood output generated by the error correction decoding in multimedia demultiplexer is fed back to the decoding in wireless interface and the decoding procedure is iterated. The performances were evaluated by MPEG-4 video transmission simulation over mobile channels.
