Classification: CPC H | IPC H

Claim 15:
16. The receive end according to claim 15, wherein the programming instructions are for execution by the at least one processor to:
receive incremental redundant bits that are transmitted by a transmit end for a second time or some of the k information bits and the incremental redundant bits that are transmitted by the transmit end;
combine the incremental redundant bits to an end of the first codeword to form a second codeword; and
decode the second codeword based on a second check matrix, wherein the second check matrix is a submatrix of the first ((n—k)/Z+h) rows and the first (n/Z+h) columns in the check matrix H, a code rate of the second check matrix is equal to a second transmission code rate, and h is an integer greater than j and less than or equal to Q.
