摘要

A transmitter 100 includes an LI signaling data coder 111. In the LI signaling data coder 111, an LI signaling data generator 1021 converts transmission parameters into Li-pre signaling data and Li-post signaling data and outputs the Li-pre signaling 5 data and the Li-post signaling data, an energy dispersion unit 121 performs energy dispersion on the Li-pre signaling data and the Li-post signaling data in order, and an LI error correction coder 1022 performs error correction coding, based on BCH coding and LDPC coding, on the energy-dispersed Li-pre signaling data. This allows for randomization of a large bias in mapping data of the Li-pre signaling data and the 10 Li-post signaling data, thus solving the problem of concentration of power in a specific sample within P2 symbols. 5388921_1 (GHMatters) P90713.AU.1 23/05/2014 _C 1/38 co bz co bOO +JC c.- C0) 4- 0 0)V wV 0 D4 C:) C) 0 - ClC 0) C CD CCM bfl0 - 0 co 0) (V 0 ---4O-4, ((D b-0
