A spread spectrum communication receiver includes a plurality of fingers each including a despreader part, an inverse-orthogonal conversion part and a demodulation part. A channel combining part combines demodulated symbols of the plurality of fingers. A control part controls the plurality of fingers on the basis of orthogonal channel allocation information and channel state information so that the fingers execute a RAKE process when the channel information indicates that data to be transmitted is allocated to one orthogonal channel at a transmitter and the fingers perform parallel demodulation processes then the channel information indicates that data to be transmitted is allocated to a plurality of orthogonal channels at the transmitter.

[ What is claimed is:] [7.] A spread spectrum communication receiver comprising:a plurality of fingers each including a despreader part, an inverse-orthogonal conversion part and a demodulation part;a channel combining part which combines demodulated symbols of the plurality of fingers;a memory which stores a despread signal obtained by despreading a signal propagated through a path having a greatest receive power level; anda control part which controls the memory and the plurality of fingers so that the despread signal is read from the memory and is applied to the plurality of fingers, which fingers perform parallel demodulation processes a plurality of times within a period of a spreading code applied to the despreader part, whereby all orthogonal channels allocated at a transmitter can be demodulated within the period of the spreading code.
