Abstract:
1. A transmitter comprising: an L1 (Layer-1) signaling data generator configured to generate, from transmission parameters of a main signal, L1 signaling data storing the transmission parameters and including L1-pre signaling data and L1-post signaling data; an error correction coding unit configured to perform error correction coding on the L1-pre signaling data; an energy dispersion and error correction coding unit configured to perform energy dispersion and error correction coding on the L1-post signaling data; and a mapper configured to perform mapping on the error correction coded L1-pre signaling data and the energy-dispersed and error correction coded L1-post signaling data, wherein the L1-pre signaling data is provided to the mapper without being energy-dispersed, the energy dispersion and error correction coding unit performs the energy dispersion on the L1-post signaling data when the L1 signaling data generator stores, in the L1-pre signaling data, energy dispersion information indicating that energy dispersion has been performed, and the energy dispersion and error correction coding unit does not perform the energy dispersion on the L1-post signaling data when the L1 signaling data generator stores, in the L1-pre signaling data, energy dispersion information indicating that energy dispersion has not been performed.
