Classification: CPC H | IPC H

Claim 11:
12. The transmit end according to claim 11, wherein:
the programming instructions are for execution by the at least one processor to encode the k information bits by using a second check matrix based on a second transmission code rate R satisfying R=k/(n+h×Z) to obtain a second codeword when transmission of the first codeword fails, 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 the second transmission code rate, h is an integer greater than j and less than or equal to Q, a code length of the second codeword is (n+h×Z), and the second codeword comprises the k information bits and (n—k+h×Z) redundant bits; and
the transmitter is further configured to send incremental redundant bits to the receive end, or send some of the k information bits and incremental redundant bits to the receive end, wherein the incremental redundant bits are the (n—k+j×Z+1)th to the (n—k+h×Z)th redundant bits in the (n—k+h×Z) redundant bits.
