A Hierarchical Tansmission System using TMCC for Satellite ISDB

Abstract

Both the spectrum efficiency and the service availability are improved by introducing a hierarchical transmission technique into the satellite ISDB (Integrated Services Digital Broadcasting) on the 12GHz band. In addition, a new technique that can control the transmission schemes with TMCC (Transmission and Multiplexing Configuration Control) signal enables the ISDB signal more flexible. The signal inform the demodulator how the transmission parameters are configured. This paper discusses the effect of a hierarchical transmission and the method of multiplexing TMCC into satellite ISDB signal.
