A path detector ( 140 ) detects a plurality of multi-path waves that have satisfied a predetermined standard from reverse spread signals, a plurality of adders ( 161 ) form beams on the basis of a path, a plurality of transfer path estimating sections ( 170 ) and complex conjugate calculators ( 163 ) calculate a transfer path estimation value, and based upon the result of the estimation, carry out a weighting process in accordance with the signal amplitude and a removing process of the phase variations. Moreover, a plurality of interference amount estimating sections ( 171 ) extract the amount of interference, a plurality of normalizing sections ( 172 ) normalize the signals that have been subjected to the phase variation removing process based upon the amount of interference, an adder ( 185 ) combines all the signals that have been normalized, and a data determining section ( 190 ) determines the signal that have been combined.
