摘要：We propose a digital transmission system for satellite broadcasting using the 12-GHz broadcasting satellite service (BSS) band. The system needs to provide high-quality and new digital services, which have not been possible in analog systems. In addition, it should take into account the improvement to the current satellite broadcasting system of the service grade, since the current system already has more than ten million receivers. The new system introduces trellis-coded 8PSK as a main modulation scheme to improve the spectrum efficiency for transmitting multi-channel HDTV and TMCC (Transmission Multiplex Configuration Control) signals so as to flexibly control the modulation scheme, It also introduces a hierarchical transmission to secure high service availability. Some necessary gate arrays for a suitable demodulator for the system have been developed.
