SIGNAL TRANSMISSION METHOD OF CTC FOR SATELLITE MOBILE COMMUNICATION SYSTEM WHICH SIMULTANEOUSLY SUPPORTS BROADCAST SERVICE AND COMMUNICATION SERVICE AND THE CTC

摘要

Provided are a signal transmission method of a complementary terrestrial component (CTC) for a satellite mobile communication system that simultaneously supports a broadcast service and a communication service, and the CTC. The CTC simultaneously receives communication data that is data for an interactive communication service and broadcast data that is data for a broadcast service from a transmitter through different frequency bands, i.e., different carriers, or the same frequency bands, i.e., the same carriers, adds additional data, and transmits the broadcast data and the additional data to terminals through different frequency bands or the same frequency bands. In this way, the satellite mobile communication system including the CTC can effectively support the interactive communication service and the broadcast service at the same time.
