<p>PROBLEM TO BE SOLVED: To secure excellent communication quality in data transmission using an LDPC code.SOLUTION: In group-wise interleave, LDPC codes with code length N of 64800 bits and a coding rate r of 9/15, 11/15, or 13/15 are interleaved by the bit group of 360 bits. In group-wise de-interleave, the arrangement of LDPC codes after group-wise interleave is returned to original arrangement. The present technique can be applied to, for example, the case where data transmission and the like using LDPC codes are performed.</p> |
