LOW DENSITY PARITY CODE ENCODING DEVICE AND DECODING DEVICE USING AT LEAST TWO FREQUENCY BANDS

摘要

PURPOSE: An encoding device and a decoding device for a low density parity code are provided to perform an encoding and decoding technique for a low density parity code by generating parity bits and data bits through a low density parity code and a parity check matrix. CONSTITUTION: An information obtaining part(712) obtains state information of at least two frequency bands. A matrix generating part(713) adaptively generates a parity check matrix based on the state information. The parity check matrix includes sub matrixes corresponding to each frequency band. An encoder generates parity bits and data bits through a low density parity code and the parity check matrix. The data bits and the parity bits are transmitted to a decoding device(720) for the low density parity code through a wireless channel.
