DATA PROCESSING APPARATUS AND DATA PROCESSING METHOD Russian patent published in 2016 - IPC H03M13/29 H04L1/00 

FIELD: information technology.

SUBSTANCE: invention relates to data processing. For this purpose, in a transmitting device padding module 21 pads control data necessary for demodulation with zeros as dummy data, and scrambling module 101 performs scrambling of said control data padded with dummy data (padded control data). Replacement module 121 performs replacement scrambled dummy data composed of scrambled padded with dummy data control data, and module 22 encoding code Bose-Chaudhuri-Hocquenghem (BCH-code) and module 23 encoding code, low density parity check (LDPC-code) encodes BCH-code coding and LDPC-code as an encoding of error correction code applied to substituted data obtained as a result of replacement. Reduction module 21 performs reduction by removing dummy data contained in LDPC-code and puncturing parity bits from LDPC-code.

EFFECT: technical result consists in simplifying processing of control data having improved peak to average power ratio (PAPR).
