ABSTRACT:
In a receiving apparatus, two respective reference-point computing units in respective diversity branches calculate reference points on a constellation, and two respective reference-point specifying units in the two diversity branches select respectively the reference points closest to the received data. A diversity circuit receive from the two diversity branches the information specifying the received data and the reference points, and a comparison processing unit compares these reference points. If these reference points are matched, a selection combining unit outputs the reference point while, if not matched, any one of received data selected at random is outputted.
