Abstract: 입력된 통신방송 융합(triple play) IP 데이터를 인터넷 및 TV 데이터와 음성(VoIP) 데이터로 나누어, 긴 지연시간을 허용하는 인터넷 및 TV 데이터는 기존의 DVB-S2 규격으로 부호화하고, 짧은 지연시간만을 허용하는 음성 데이터는 DVB-RCS +M 규격 기반의 4K 모드로 부호화한다. 부호화된 데이터는 각각 직교 변조되고, 직교 변조된 음성 데이터는 확산 계수(spreading factor)에 따라 직접수열 기반으로 대역 확산된다. 대역 확산된 신호는 SCPC(FDMA: frequency division multiple access) 형태로 각 사용자별로 할당된 주파수와 중첩되도록 다중화된다.
