ABSTRACT:
A mobile phone1receives a home cell signal sent from a base station B1and a foreign cell signal sent from a base station B2or from a mobile phone21in a foreign cell A2. The mobile phone1receives spreading codes C2–C4sent from the base station B1, as home cell codes. The mobile phone1detects the interference between the home cell signal and the foreign cell signal. When the interference is detected, the mobile phone1receives a spreading code C1sent from the base station B2or from the mobile phone21, as a foreign cell code. The mobile phone1cancels an interference signal by joint detection, using the home cell codes and the foreign cell code.
