Abstract

Transmission methods for terrestrial UHDTV broadcasting have been actively studied in order to provide enhanced broadcasting service in many countries. Most of the countries are considering multi-carrier transmission methods based on OFDM and some of them have performed UHDTV experimental broadcasting by using the DVB-T2 standard with the adoption of an improved data compression technique. However, since single carrier transmission methods, which are known to be susceptible to multi-path fading, could remedy this defect by using the SC-FDE method where a frequency domain equalizer is utilized in the receiver, they may achieve a similar transmission performance with multi-carrier transmission methods. In consideration of these circumstances, we compare the transmission performances of two-type methods to provide a decision criterion on a suitable transmission method for UHDTV broadcasting.

세계 여러 나라들은 향상된 방송 서비스를 제공하기 위해서 지상파 UHDTV (Ultra High Definition Television) 전송방식에 관한 연구를 진행하고 있으며, 대부분이 다중경로에 강건한 OFDM (Orthogonal Frequency Division Multiplexing) 기반의 다중 반송파 전송방식을 고려하고 있다. 일부 국가에서는 이를 기반으로 하는 DVB-T2 (Digital Video Broadcasting 2nd generation Terrestrial) 표준에 향상된 대용량 데이터 압축기술을 더해 UHDTV 실험 방송을 진행 중이다. 그러나 다중경로에 취약하다고 알려진 단일 반송파 전송방식에서도 수신기에서 주파수 영역에서 채널 등화를 수행하는 SC-FDE (Single Carrier-Frequency Domain Equalizer)를 사용하면 이러한 단점을 보완할 수 있기 때문에, 두 방식 간의 성능 차이가 미미하게 나타난다. 이를 고려해 본 논문에서는 UHDTV 방송을 위해서 고차 신호 성상을 전송하는데 다중 반송파와 단일 반송파 중 어느 방식이 적합한지에 대한 판단 근거를 제공하고자 두 방식의 수신 성능을 비교한다.
