Abstract:
1. A method for forming a beam of an array antenna to direct a null point of the array antenna at a mobile station which acts as interference, comprising: calculating a signal power to interference power ratio of the mobile station acting as interference and a signal power to interference power ratio of the mobile station acting as interference after a movement of the mobile station acting as interference, based on a moving speed and a moving direction of the mobile station acting as interference as well as a distance between the array antenna and the mobile station acting as interference, in each of respective cases where the distance between the array antenna and the mobile station acting as interference is different; and forming a beam to equate the signal power to interference power ratios calculated in the respective cases to one another where the distance between the array antenna and the mobile station acting as interference is different before and after the movement of the mobile station acting as interference.
