초록

본 논문에서는 ATSC 8-VSB 전송방식과 하위호환성을 유지하며, 수신성능을 비약적으로 개선시킨 Enhanced-xVSB 1/4 rate robust modulation 방식을 제안한다. Enhanced-xVSB 1/4 rate 모드는 보행 및 이동수신을 위해 데이터 전송량 및 수신성능개선의 상호 trade-off를 방송사측에 폭넓게 제공한다. Enhanced-xVSB 1/4 rate mode는 AWGN 및 다양한 multipath fading환경에서의 VSB수신성능을 비약적으로 발전시켰으며, 본 논문에서는 Enhanced-x VSB 지상파 전송시스템을 보행, 이동수신을 위한 ATSC 차세대 전송방식으로 제안한다.

In this paper, we describe a new 1/4 rate robust modulation techniques for Enhanced-x VSB system which is fully backward compatible with ATSC 8-VSB standard. 1/4 rate mode Enhanced-xVSB system provides broadcasters with a wide choice of trade-offs of data rate vs amount of robustness of enhanced data for pedestrian/mobile services. Lab test results of proposed Enhanced-x VSB 1/4 rate mode robust stream are a significantly improved multipath as well as AWGN reception performance for Enhanced-x VSB receiver. We suggest an Enhanced-x VSB terrestrial broadcasting system for ATSC HDTV and pedestrian/portable TV simultaneous broadcasting service providing.
