Estimating the term…
A data signal component output from a reference signal demultiplexer and channel state information obtained by using DM-RS output from a channel estimating unit are input into a modulo estimating unit. In a channel compensator, a first provisional decision value sequence is calculated on the basis of the channel state information. The first provisional decision value sequence is input into a modulo calculator, and modulo calculations are performed on the first provisional decision value sequence to obtain a second provisional decision value sequence. A decision-feedback channel estimating section finds a first channel estimation value based on the first provisional decision value sequence and a second channel estimation value based on the second provisional decision value sequence. A modulo decision section decides whether or not a perturbation term has been added to a code, and uses a decision result for the selection of a demodulation method.
