최근 스마트폰과 태블릿 PC동 고해상도 모바일 단말기 보급이 급격히 늘어남에 따라 고화질 및 다양한 서비스 제공이 가능한 모바일 방송에 대한 요구가 급증하고 있다. 이러한 요구에 맞춰 T-DMB와 역호환성을 유지 하면서 기존의 T-DMB와는 달리 계층변조 방식을 적용해 동일 주파수 대역에서 최대 2배의 채널 용량을 증대시키는 AT-DMB 방송기술 개발을 완료하였다. AT-IDMB는 채널 용량의 증대에 따라 서비스 채널을 늘리거나 고화질 서비스 동을 추가로 제공할 수 있게 되었고 사용자와 DMB 사업자들의 요구를 충족 시켜줄 수 있게 되었다. 본 논문은 정지 환경에서 수행한 AT-DMB의 성능 측정 결과를 보여준다.
