PROBLEM TO BE SOLVED: To prevent deterioration in interference eliminating characteristics for improving accuracy in an interference eliminating CDMA multiuser receiver that eliminates interference to the user signal of a plurality of movement terminals, and outputs the demodulation signal of each user signal. SOLUTION: An interference replica generated at a replica generation section 9-21 is accumulated in a data accumulation buffer 1-12, a write/read control part 1-2 controls the write and read of the data accumulation buffer 1-12 based on data reception timing interval information measured by a data reception timing interval measurement section 1-3, difference at the timing position of data to be calculated due to the reception timing fluctuation between the interference replica and delayed reception data is absorbed, and the interference is eliminated by an interference replica subtraction section 9-12. Also, based on the data reception timing interval information, an interference eliminating prohibition signal generation section 1-4 prevents the elimination of an indefinite interference replica at the interference replica subtraction section 9-12. |
