차세대 케이블 텔레비전 방송을 위한 오픈 케이블 시스템에 관한 연구

Recently near Shannon limit error correct codes (turbo, LDPC codes) and multi-level modulation schemes such as over 1024 QAM are applied for bandwidth efficient next generation cable television broadcasting. In this manner, we study multi-level QAM transmission based on Open Cable systems. This paper presents the potential of next generation cable television broadcasting.
