Abstract

Determination of an impairment compensation matrix for compensation of impairments in an antenna array is disclosed. A plurality of different combinations of multi signal transmissions which form at least one null at a respective location of a plurality of locations is determined. Each combination includes a multi signal transmission that comprises at least two concurrent signal transmissions from at least two antenna subarrays of N antenna subarrays and the respective location. Based on signal characteristics associated with the plurality of different combinations of multi signal transmissions and an expected signal reception at the plurality of locations an impairment matrix that identifies an effect of impairments among the N antenna subarrays is determined. The impairment compensation matrix is determined based on the impairment matrix.
