Abstract
The present invention relates to a data processing device and a data processing method for reducing peak to average power ratio (PAPR) and for limiting the modification and complexity necessary for achieving the PAPR reduction in a classical DVB-T2 receiver.Control data are first scrambled. Then the scrambled control data are padded with dummy bits.The scrambled data and the padding bits undergo concatenated coding, the concatenated coding consisting first of Bose-Chaudhuri-Hocquenghem, BCH, encoding and then of Low Density Parity Check, LDPC, encoding. Prior to transmission and in order to limit the amount of transmitted bits, parity bits of the LDPC code are punctured and dummy data are removed from the transmitted data.A frame is built containing the punctured LDPC and BCH coded scrambled control data without padding bits, a preamble in the frame including a symbol including information that the frame contains the punctured LDPC and BCH coded scrambled control data without padding bits, and the frame is multiplexed in a DVB-T2 signal.
