PURPOSE: To prevent operation for estimating the quantity of interference from being increased even when a received signal is band-limited by an over-sampling filter. CONSTITUTION: Each of decimation filter parts 51(1) to 51(3) for respective waves down-samples a received signal to a diffusion speed corresponding to a spreading code allocated to a corresponding mobile station. A replica for transmitting data from the corresponding mobile station is generated based upon a down-sampling output through a correlation detecting part 52, a phase correcting part 53, an amplitude correcting part 54, an adder part 55, and a decision part 56. A rediffusion part 57 rediffuses the replica and an over- sampling filter part 58 limits the band of the rediffused output similarly to the corresponding mobile station. A replica for the diffused modulation output of the transmitting data from the corresponding mobile station is generated through a delay part 59, a phase correcting part 60, an amplitude correcting part, and adder parts 62, 63. |
