<P>PROBLEM TO BE SOLVED: To provide a technique for improving a decoding characteristic of block-turbo-coded data. <P>SOLUTION: A block turbo decoding section 50 executes iterative decoding of input data by the Pyndiah algorithm. A weight coefficient storage section 52 stores as a plurality of types of weight coefficient patterns a plurality of combinations of weight coefficients by which to multiply external values derived by the Pyndiah algorithm during the iterative decoding executed in the block turbo decoding section 50. A weight coefficient control section 56 selects any one from the plurality of types of weight coefficient patterns, and selects one weight coefficient from the selected weight coefficient pattern for each iteration cycle to be used in the block turbo decoding section 50. <P>COPYRIGHT: (C)2013,JPO&INPIT |
