Abstract
The invention relates to a data processing apparatus and a data processing method that can easily perform control processing has been improved PAPR of data to it. In the transmission apparatus of the invention the filler (21) is used as the zero of the dummy fill data execution control data demodulation required whereupon the scrambler (101) control data after the filling control data (after filling) to perform scrambling. filling replacing unit (121) replaced by dummy data after the scrambling control scrambling of the dummy data whereupon BCH encoder (22) and the LDPC encoder (23) respectively performing BCH coding and LDPC coding as the substitute data obtained by replacing the error correction coding. cutting unit (21) performing LDPC code included in the deletion of dummy data and check bit of the LDPC code as punctured. 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.
