Abstract
A mobile phone 1 receives a home cell signal sent from a base station B1 and a foreign cell signal sent from a base station B2 or from a mobile phone 21 in a foreign cell A2. The mobile phone 1 receives spreading codes C2–C4 sent from the base station B1, 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 C1 sent from the base station B2 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.
