PROBLEM TO BE SOLVED: To provide a data processor capable of ensuring satisfactory communication quality in data transmission using LDPC code.SOLUTION: In a groupwise interleave, the code length N is 64800 bits and LDPC code the encoding rate r of which is 7/15, 9/15, 11/15 or 13/15 is interleaved with a bit group unit of 360 bits. In the groupwise deinterleave, LDPC code array after groupwise interleave is restored to an original array. The technique is applicable to, for example, data transmission using LDPC code. |
