Abstract
A transmitter according to the disclosure includes: an encoding unit that generates a code word by performing coding with a low-density parity-check code using a check matrix, the encoding unit being capable of switching the check matrix for use in generating the code word, between a first check matrix with a first code rate and a second check matrix with a second code rate smaller than the first code rate, the first check matrix containing a plurality of cyclic permutation matrices, the encoding unit generating the second check matrix by masking the cyclic permutation matrix at a predetermined position in the first check matrix and adding a row with a column weight equal to or less than a threshold; and a transmission unit that transmits the code word.
