ABSTRACT:
A decoding device for decoding digital signals that are transmitted after being processed separately blockwise, performs error interpolation by using only the data within a block where the code error has occurred, in such a manner that the adverse effect of using the data of other blocks for an error interpolation in the vicinity of the block boundary may be avoided, and the error interpolation may be attained by a shorter operating word length in advance of blockwise decoding.
