Abstract: A searcher detecting signal indicating conditions of propagation paths is detected from incoming waves of a pilot signal transmitted at the highest electric power. In a RAKE reception for one code channel, an interference replica signal functioning as an interference signal for an incoming wave of the code channel to be demodulated in one finger unit is produced from reference signals produced in the other finger units and the searcher detecting signal, an interference removal is performed for a receiving signal according to the interference replica signal, and the demodulation of the RAKE reception is performed. In the demodulation based on a plural code channel, a reference signal is produced in one of the finger units, an interference replica signal is produced from the reference signal and the searcher detecting signal, an interference removal is performed for the receiving signal according to the interference replica signal, and the demodulation based on the plural code channel is performed.
