Abstract
A likelihood generation device includes a similarity detection unit, a likelihood table reference unit, and a similarity processing unit. The similarity detection unit receives a modulation scheme selection signal and a received value, detects a likelihood similarity between information bits included in the received value based on the modulation scheme selection signal, and outputs a likelihood selection signal that specifies likelihood data to be searched for and an operation selection signal that specifies an operation on the likelihood data. The likelihood table reference unit registers, as likelihood data, a small region different from other small regions in the likelihood distribution indicating the likelihood of the information bits, and extracts likelihood data based on the likelihood selection signal from the likelihood table. The similarity processing unit obtains the entire likelihood distribution by performing an operation designated by the operation selection signal on the extracted likelihood data.
