Data processing device and data processing method

摘要

A data processing device and a data processing method that can readily process control data having its PAPR improved. In a transmission device, a padder pads control data necessary for demodulation with zeros as dummy data, and a scrambler scrambles the padded control data (post-padding control data). A replacement unit replaces scrambled dummy data in the scrambled post-padding control data with the dummy data, and a BCH encoder and an LDPC encoder perform BCH encoding and LDPC encoding as error correction encoding on the replacement data obtained through the replacement. A shortening unit performs shortening by deleting the dummy data contained in the LDPC code and puncturing the parity bits of the LDPC code. The device can be applied in cases where control data is subjected to error correction encoding and is then transmitted, for example.

主权项

1. A data processing device for processing control data prior to aggregation of said control data with payload data in a data frame for transmission, comprising:
circuitry configured to pad control data directly with dummy data, the control data being necessary for demodulation; scramble post-padding control data, the post-padding control data being the padded control data; generate replacement data by replacing scrambled dummy data in the scrambled post-padding control data with the dummy data; and perform error correction encoding on the replacement data.
