Abstract
An apparatus may include a transmitter and one or more processors. The one or more processors may identify, based on a first parity check matrix of a first quasi-cyclic-low-density parity-check (QC-LDPC) code according to a code rate of 3/4, a second parity check matrix corresponding to a first exponent matrix comprising 576 values for a second QC-LDPC code. The second QC-LDPC code may have a code block size that is twice a code block size of the first QC-LDPC code. The one or more processors may encode data using the second parity check matrix. The transmitter may be configured to transmit the encoded data.
Claims20
A method, comprising:
- identifying, by one or more processors of a first device based on a first parity check matrix of a first quasi-cyclic-low-density parity-check (QC-LDPC) code according to a code rate of 3/4, a second parity check matrix corresponding to a first exponent matrix comprising 576 values for a second QC-LDPC code, wherein the second QC-LDPC code has a code block size that is twice a code block size of the first QC-LDPC code, and at least 574 values are selected, as values of the first exponent matrix, from values of a second exponent matrix having the same dimensions as dimensions of the first exponent matrix;
- encoding, by the one or more processors of the first device, data using the second parity check matrix;
- and
- transmitting, by the one or more processors of the first device, the encoded data.
An apparatus comprising:
- a transmitter and one or more processors, wherein
- the one or more processors are configured to:
- identify, based on a first parity check matrix of a first quasi-cyclic-low-density parity-check (QC-LDPC) code according to a code rate of 3/4, a second parity check matrix corresponding to a first exponent matrix comprising 576 values for a second QC-LDPC code, wherein the second QC-LDPC code has a code block size that is twice a code block size of the first QC-LDPC code, and at least 574 values are selected, as values of the first exponent matrix, from values of a second exponent matrix having the same dimensions as dimensions of the first exponent matrix;
- and
- encode data using the second parity check matrix, and
- the transmitter is configured to transmit the encoded data.
An apparatus comprising:
- a receiver configured to receive encoded data;
- and
- one or more processors configured to:
- identify, based on a first parity check matrix of a first quasi-cyclic-low-density parity-check (QC-LDPC) code according to a code rate of 3/4, a second parity check matrix corresponding to a first exponent matrix comprising 576 values for a second QC-LDPC code, wherein the second QC-LDPC code has a code block size that is twice a code block size of the first QC-LDPC code, and at least 574 values are selected, as values of the first exponent matrix, from values of a second exponent matrix having the same dimensions as dimensions of the first exponent matrix;
- and
- decode the received encoded data using the second binary parity check matrix.
