摘要： Disclosed is a transmission device in a communication system in which a systematic code obtained by systematic encoding of information bits into which dummy bits are inserted and by deleting the dummy bits from the results of the systematic encoding is transmitted and, on the receiving side, the dummy bits which had been deleted on the transmitting side are inserted into the received systematic code, and then decoding is performed. In this transmission device, a dummy bit insertion portion decides the size of the dummy bits to be inserted into the information bits based on a specified code rate or based on the physical channel transmission rate, and uniformly inserts dummy bits of this size into the information bits; a systematic code generation 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 systematic encoding to generate a systematic code, which is transmitted.

摘要： A check matrix generation method for generating a check matrix H1 of a code H1 from a check matrix H0 of a code C0, where codes C0 and C1 are LDPC systematic codes having different encoding ratios in a rate-compatible relationship and information bit sizes of the systematic codes C0 and C1 are K, and parity bit sizes thereof are M0 and M1 (M1−M0=L) respectively. The method comprising steps of: selecting L number of rows out of the check matrix H0; separating an information bit portion and a parity bit portion constituting each of the selected rows into two respectively, such that each of the separated information bit portions includes one or more non-zero elements which are “elements different from 0”; creating a new first row by coupling one separated information bit porting and one separated parity bit portion and creating a new second row by coupling another separated information bit portion and another separated parity portion; and generating the check matrix H1 of the systematic code C1 by placing the new first and second rows in place of each of the selected L number of rows in the check matrix H0.
