Abstract  Abstract

The invention relates to a data processing apparatus and a data processing method which can easily perform control of data processing has been improved PAPR. In the transmission apparatus of the invention the filler (21) is used as the zero padded dummy data control data needed for demodulation is performed whereupon the scrambler (101) after filling of the filled control data (control data) to perform scrambling. filling substituter unit (121) for replacing the dummy data after scrambling control scrambling of the dummy data whereupon a BCH encoder (22) and the LDPC encoder (23) respectively performing BCH coding and LDPC coding as replacement of the error correction coding data obtained by replacing. LDPC code included in the dummy data deletion and the check bit of the LDPC code as the puncturing cutting is performed by the cutting unit (21). For example in order to send them when the control data for error correction can be applied to the present invention.

The present invention relates to a data processing device and data processing method capable of easily performing processing of control data for which the PAPR has been improved. In a transmission device of the present invention a padder (21) pads control data required for performing demodulation with zeros which are dummy data whereupon a scrambler (101) performs scrambling for the control data after padding (post-padding control data). A replacer unit (121) replaces the scrambled dummy data among the post-padding control data after scrambling with dummy data whereupon a BCH encoder (22) and an LDPC encoder (23) perform BCH encoding and LDPC encoding respectively as error-correction coding of the replaced data acquired by the replacement. A truncation unit (21) performs deletion of the dummy data included in the LDPC code and truncation which is puncturing of the parity bits of the LDPC code. The present invention can be applied for example when error-correcting the control data in order to transmit thereof.
