First Claim
1. A method for determining an impairment compensation matrix for compensation of impairments in an antenna array comprising N antenna subarrays, comprising:
- determining a plurality of different combinations of multi-signal transmissions which form at least one null at a respective location of a plurality of locations, each different combination comprising;
a multi-signal transmission that comprises at least two concurrent signal transmissions from at least two antenna subarrays of the N antenna subarrays, the at least two concurrent signal transmissions having associated signal characteristics; and
the respective location;
based on the signal characteristics associated with the plurality of different combinations of multi-signal transmissions and an expected signal reception at the plurality of locations, determining an impairment matrix that identifies an effect of impairments among the N antenna subarrays; and
determining the impairment compensation matrix based on the impairment matrix.

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.
