Abstract
A method for forming a beam in an array antenna to orient a null point of the array antenna to a mobile station which acts as interference, includes the step of: forming a beam in such a manner that, based on a moving speed of the mobile station acting as interference, a moving direction and a distance between the array antenna and the mobile station, a signal power to interference power ratio may be equal, regardless of the distance, between before and after movement when the mobile station acting as interference moves.
