APPARATUS AND METHOD FOR INTERLEAVING, APPARATUS AND METHOD FOR SOFT-OUTPUT DECODING, AND APPARATUS AND METHOD FOR DECODING

摘要

PROBLEM TO BE SOLVED: To, when a plurality of symbols are inputted and a plurality of symbols are outputted, decode codes different only in the order between input symbols and/or the order between output symbols. SOLUTION: An element decoder 50I deinterleaves data outputted from a soft-output decoding circuit 90 through an interleaver 100. At this time the element decoder 50I changes the order of symbols of interleaver output data IIO comprising a plurality of symbols according to code configuration through a symbol changing circuit 610 and supplies the symbols to an element decoder 50J. The element decoder 50J interleaves data soft-output-decoded, through the interleaver 100. At this time the element decoder 50J changes the order of the symbols of data I comprising a plurality of symbols according to code configuration through a symbol changing circuit 611 and supplies the symbols as data IR to the storage circuits 407.
