A demodulator device of the present invention receives a propagation signal including a plurality of channel signals multiplexed with each other, that is modulated by using an orthogonal code sequence, through different propagation paths. The demodulator device includes propagation path estimators for performing operations including propagation path estimation and demodulates the received propagation signal by subjecting outputs of the propagation path estimators to multi-path combination. More specifically, for information obtained by correlators corresponding to operations, the demodulator device performs the multi-path combination by combining results of multiplications of the outputs of the propagation path estimators for correlation values and then separate the plurality of channels.
