Patent ID: 11283534

Abstract:
The interference power estimation apparatus 1 calculates an inter-station vector from an interfering station over a sphere to an interfered station installed in the sphere based on a position of each station. In a case where a line segment connecting the position of the interfered station and the position of the interfering station does not intersect with the sphere, an angle between an antenna direction vector representing a direction of an antenna from the position of the interfered station and the inter-station vector is derived, and a sum of an antenna directivity attenuation amount obtained based on the angle and propagation losses calculated based on a distance between the interfered station and the interfering station is calculated. The interference power estimation apparatus 1 calculates the sum for each of a plurality of possible positions of the interfering station, but does not calculate the sum in a case where the line segment connecting the position of the interfered station and the position of the interfering station intersects with the sphere. The interference power estimation apparatus 1 calculates interference power from the interfering station, based on a minimum value of the calculated sum.
