ABSTRACT:
A data signal processing apparatus is capable of reproducing original data with a small number of repetition times of an iterative decoding process, which is realized by likelihood information operating means that generate updated likelihood information, carry out a predetermined operation on a plurality of pieces of likelihood information corresponding to the original data obtained by the iterative decoding process, and reproduce the original data.
