A selector 301 select one a directional signal corresponding to a group to which a transmission signal belongs on a path-by-path basis. A despreader 302 provides despreading to an output signal of the selector 301. A RAKE combiner 305 provides RAKE combing to a despread signal, and a determining device 306 provides temporary determination to the signal subjected to RAKE combing. A re-spreader 308 spreads a replica signal subjected to temporary determination. A divider 309 divides replica signals on a path-by-path basis to correspond to the directivity selected by the selector 301. Adders 310-1 and 310-2 add the replica signals divided by the divider 309 on the directivity-by-directivity. This makes it possible to cancel interference in combination with an array antenna and to reduce the number of calculations and the circuit scale as an entirety of the apparatus.
An interference canceling apparatus comprising:
A base station apparatus having an interference canceling apparatus, said interference canceling apparatus comprising.
An interference signal canceling method comprising the steps of:
