A mobile phone 1 receives a home cell signal sent from a base station B 1 and a foreign cell signal sent from a base station B 2 or from a mobile phone 21 in a foreign cell A 2 . The mobile phone 1 receives spreading codes C 2 -C 4 sent from the base station B 1 , as home cell codes. The mobile phone 1 detects the interference between the home cell signal and the foreign cell signal. When the interference is detected, the mobile phone 1 receives a spreading code C 1 sent from the base station B 2 or from the mobile phone 21 , as a foreign cell code. The mobile phone 1 cancels an interference signal by joint detection, using the home cell codes and the foreign cell code.
