摘要： The present technology relates to a data processing device and a data processing method which can ensure high communication quality in data transmission using LDPC codes.
In group-wise interleaving, an LDPC code having a code length N of 64800 bits and a coding rate r of 13/15 is interleaved in a unit of a bit group of 360 bits. In group-wise deinterleaving, a sequence of bit groups of the LDPC code which has been subjected to the group-wise interleaving is returned to an original sequence. The present technology can be applied to, for example, a case in which data transmission is performed using LDPC codes.

摘要： In group-wise interleaving, interleaving of an LDPC code having a code length N of 64800 bits and an encoding rate r of 5/15 is performed in a unit of a bit group of 360 bits. In group-wise deinterleaving, an arrangement of the LDPC code that has undergone group-wise interleaving is returned to an original arrangement. The technology can be applied to a case of transmitting data using the LDPC code. The data processing device and data processing method can ensure excellent communication quality in data transmission using an LDPC code.

摘要： The present technology relates to a data processing device and a data processing method, which are capable of securing excellent communication quality in data transmission using an LDPC code. In group-wise interleave, an LDPC code in which a code length N is 16200 bits and an encoding rate r is 6/15, 8/15, or 10/15 is interleaved in units of bit groups of 360 bits. In group-wise deinterleave, a sequence of the LDPC code that has undergone the group-wise interleave is restored to an original sequence. For example, the present technology can be applied to a technique of performing data transmission using an LDPC code.

摘要： The present technology relates to a data processing device and a data processing method capable of securing excellent communication quality in data transmission using an LDPC code. In group-wise interleave, an LDPC code having a code length N of 64800 bits and a coding rate r of 9/15, 11/15, or 13/15 is interleaved in units of bit groups of 360 bits. In group-wise deinterleave, a sequence of LDPC codes after the group-wise interleave is returned to an original sequence. The present technology, for example, can be applied to a case where data transmission using an LDPC code or the like is performed.
