A communication apparatus calculates a residual component by noting one of a given plurality of transmitted signals and by canceling a component corresponding to a candidate/candidates for the other/others of the plurality of transmitted signals from a signal corresponding to one of a plurality of received signals. The communication apparatus determines a candidate for the given transmitted signal by selecting a value closest to the residual component from among the values that the given transmitted signal can take, and obtains a plurality of candidate groups by changing that given transmitted signal, each candidate group being constructed as a collection of candidate sets each comprising a candidate for that given transmitted signal and a candidate/candidates for that other transmitted signal/signals. Then, the communication apparatus selects transmitted signal candidate sets that are common to the plurality of candidate groups and estimates the plurality of transmitted signals using the selected candidate sets. |
