DETERMINATION OF AN IMPAIRMENT COMPENSATION MATRIX FOR AN ANTENNA ARRAY
摘要
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.
