Abstract
A transmission device and reception device for digital data that have excellent resistance to noise are provided. An encoder (-) of this disclosure, included in a transmission device () of this disclosure, applies LDPC encoding to digital data using a unique check matrix for each code rate by using a check matrix in which, taking a check matrix initial value table established in advance for each code rate at a code length of 44880 bits as initial values, 1 entries of a partial matrix corresponding to an information length appropriate for a code rate of 93/120 are allocated in the column direction over a cycle of 374 columns. A demodulator () of this disclosure, included in a reception device () of this disclosure, decodes digital data encoded by the encoder (-).
