A new transmission system for the advanced satellite broadcast
Akinori Hashimoto, Yoichi Suzuki · IEEE Transactions on Consumer Electronics · 2008
Current satellite digital broadcasting transmission system "ISDB-S" employs digital modulation schemes, BPSK, QPSK, and 8PSK combined with a concatenated code consists of convolution code and Reed-Solomon code. While, in recent years, transmission systems adopted LDPC codes have been developed. Multi-level digital modulation schemes combined with LDPC codes can achieve more efficient transmission. In this paper, we propose a new transmission system employed LDPC, multi-level modulation and advanced TMCC signal1.
