Abstract:
1. A receiving unit for receiving a CDMA system signal having a plurality of multipath components, the receiving unit comprising: a receiving section for receiving a CDMA system signal; a storage section for storing the signal received by the receiving section; a demodulation section for demodulating each of multipath components included in the received signal stored in the storage section with a despreading code; a control section to provide control for demodulating a plurality of the multipath components by causing the demodulation section to perform a time division multiplex process; and a Rake combining section for performing the maximal ratio combining of output from the demodulation section to generate a demodulated signal, wherein the demodulation section divides the timing with which the signal is read from the storage section into 2N time slots, assigns N of the 2N time slots to an ordinary despreading process, and assigns the remaining N time slots to a despreading process for preventing a symbol from being lost at the time of the variation in the timing of the received signal.
