<p><P>PROBLEM TO BE SOLVED: To provide a low density parity code (LDPC) encoding/decoding device and method, capable of considering frequency selective properties of wireless channels, by adaptively generating a parity check matrix in accordance with statuses of a plurality of frequency bands. <P>SOLUTION: The LDPC encoding device includes: an information obtaining unit which obtains status information of at least two frequency bands; a matrix generating unit which generates a parity check matrix on the basis of 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 by using the LDPC with the parity check matrix generated. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
