Abstract

In this paper, we propose transmission systems for ultra high definition television (UHDTV) through terrestrial transmission by applying the multi-input multi-output (MIMO) technology. The space time block code, hybrid STBC, V-BLAST and linear dis- persion code are considered to support a high data rate of the UHDTV system. The performance of proposed MIMO systems are evaluated through computer simulations. Then we suggest MIMO parameters, number of antennas and optimal transmission scheme to achieve the transmission rate of the UHDTV system.

본 논문에서는 MIMO(multi-input multi-output) 시스템을 적용하여 지상파 UHDTV 시스템을 구현하기 위한 전송 시스템을 제시하였다. 차세대 UHDTV 시스템이 필요로 하는 높은 전송량을 달성하기 위하여 기존의 MIMO(multi input multi output) 전송 방식인 STBC(space time block code), 하이브리드 STBC, V-BLAST 및 선형분산코드(linear dispersion matrix)를 이용한 송신 기법을 고려하였다. 이 중에서 대표적인 세 가지 MIMO 전송 기법의 심볼 오류 성능 및 복잡도를 컴퓨터 시뮬레이션을 통하여 평가하였다. 이를 통하여 UHDTV 시스템의 전송량을 달성하기 위한 최적의 송 수신 안테나 개수와 MIMO 파라미터 제시 및 세 개의 MIMO 전송 기법의 장단점을 비교 분석하여 가장 적합한 시스템을 제안하였다.
