Abstract: A wireless communication apparatus outputs first and second beams, based on a weighting vector representing gain and/or phase weighting. The apparatus derives a weighting vector corresponding to a maximum eigen value of a matrix obtained by subtracting, from a first matrix representing a main lobe output power of the first beam, a matrix obtained by multiplying a second matrix representing a side lobe output power of the first beam to a reduction ratio for reducing the side lobe output power of the first beam interfering with a main lobe of the second beam. The apparatus determines whether or not a power ratio of the main lobe output power of the first beam with respect to the side lobe output power of the first beam is greater than a maximum SIRmax, and extracts the weighting vector when the power ratio is not larger than the maximum SIRmax.
