Abstract
A reception device includes: a polarization separating unit configured to perform polarization-separation on reception signals respectively corresponding to an X-polarized wave a the Y-polarized wave, output from a receiving unit; a first signal decoding unit configured to decode a single-sequence transmission signal from the given reception signals; a second signal decoding unit configured to decode a two-sequence transmission signal from the given reception signals; and a reception signal comparison unit configured to determine whether change patterns in the reception signals respectively corresponding to the X-polarized wave and the Y-polarized wave separated by the polarization separating unit are similar to each other, output the reception signals obtained by polarization-separation by the polarization separating unit to the first signal decoding unit in a case where the change patterns are similar to each other, and output the reception signals obtained by polarization-separation by the polarization separating unit to the second signal decoding unit in a case where the change patterns are not similar to each other.
