Abstract
Disclosed is a transmission device which transmits a systematic code obtained by adding parity bits to information bits. When the code rate of the systematic code is a value in a specific range determined by the decoding characteristic in a case where dummy bits are not inserted, a dummy bit insertion portion inserts dummy bits into the information bits and shifts the decoding characteristic, so that the code rate assumes a value outside a specific range determined by the decoding characteristic after shifting. An encoding portion performs systematic encoding of the information bits into which the dummy bits are inserted, and deletes the dummy bits from the results of the encoding to generate a systematic code, and a rate matching portion, performs rate matching such that the size of the systematic code is equal to a size determined by the physical channel transmission rate, and transmits the systematic code.
