Abstract
Provided is an LDPC (Low Density Parity Check) code for terrestrial cloud broadcast. A method of encoding input information based on an LDPC (Low Density Parity Check) includes receiving information and encoding the input information with an LDPC codeword using a parity check matrix, wherein the parity check matrix may have a structure obtained by combining a first parity check matrix for an LDPC code having a higher code rate than a reference value with a second parity check matrix for an LDPC code having a lower code rate than the reference value.
Claims8
A method of decoding an LDPC (Low Density Parity Check) code by an LDPC decoder, the method comprising;
- receiving a signal corresponding to an LDPC codeword;
- and
- performing decoding for the signal, the LDPC codeword corresponding to a parity check matrix, wherein the parity check matrix includes a dual diagonal matrix and an identity matrix.
An LDPC (Low Density Parity Check) decoder comprising:
- a receiving unit configured to receive a signal corresponding to an LDPC codeword;
- and
- a decoding unit configured to performing decoding for the signal, the LDPC codeword corresponding to a parity check matrix, wherein the parity check matrix includes a dual diagonal matrix and an identity matrix.
