Transmitter, transmission method, receiver, reception method, program, and integrated circuit

摘要

A transmitter (100) comprises an L1 signaling data encoder (111). In the L1 signaling data encoder (111), an L1 signaling data generator (1021) converts a transmission parameter into L1 pre-data and L1-post data for output, an energy dispersal unit (121) performs energy dispersal on the L1 pre-data and L1 post-data in order, and an L1 error correction encoder (1022) performs error correction coding on the energy dispersed L1 pre-data by BCH and LDPC coding. This makes it possible to randomize a large bias in mapping data of the L1 pre-data and the L1 post-data and thereby solve a problem wherein power concentrates onto a specific sample in a P2 symbol.
