ABSTRACT:
A receiving unit for receiving a CDMA system signal having a plurality of multipath components is intended to reduce the size. A receiving section receives a CDMA system signal. A storage section stores the signal received by the receiving section. A demodulation section demodulates each of multipath components included in the received signal stored in the storage section with a despreading code. A control section controls for demodulating a plurality of the multipath components by causing the demodulation section to perform a time division multiplex process. A Rake combining section performs the maximal ratio combining of output from the demodulation section to generate a demodulated signal.
