A low density parity code (LDPC) encoding and decoding devices and encoding and decoding methods thereof are provided. An LDPC encoding device includes an information obtaining unit which obtains status information of at least two frequency bands, a matrix generation unit which generates a parity check matrix based on the status information, the parity check matrix including sub matrices which correspond to the at least two frequency bands, and an encoder which generates data bits and parity bits using an LDPC with the generated parity check matrix. |
