<P>PROBLEM TO BE SOLVED: To increase the accuracy of decoding by implementing iterative decoding ensuring a uniform iteration count. <P>SOLUTION: An LDPC code word segmentation section 51 segments input data into single code words of LDPC decoding and outputs them to a memory 53. The memory 53 is instructed by a control section 52 to output the code words one by one to an LDPC decoding section 54. The control section 52 calculates a decoding time per code word determined by the number of code words per unit time, and controls the memory 53 such that the memory 53 outputs the code words at the time intervals. The time set by the control section 52 is the same for every code word included in one unit time, so that an iteration count of decoding in the LDPC decoding section 54 is also the same. The invention can be applied to a reception apparatus for receiving a digital broadcast wave. <P>COPYRIGHT: (C)2012,JPO&INPIT |
