Abstract
A signal shaping device includes: a generation unit to perform plural types of predetermined processes on blocks obtained by dividing plural sequences of bit strings by a predetermined length, and generate a plurality of candidate blocks that are candidates for a shaped block to be transmitted; a calculation unit to calculate, on a candidate-block-by-candidate-block basis, a weight of a one-dimensional modulation symbol when a plurality of bits included in the candidate block are converted into the one-dimensional modulation symbol; a selection unit to select, from among the candidate blocks, the shaped block on a basis of the weight; an addition unit to add, to the shaped block, selection information indicating a selection result; and a symbol mapping unit to generate a one-dimensional modulation signal by converting a plurality of bits included in the shaped block, into the one-dimensional modulation symbol.
