ANTENNA RECIPROCITY CALIBRATION
First Claim
1. A method of calibrating at least one antenna, the method comprising:
- selecting as a primary reference antenna at least a first antenna within a first antenna array;
selecting as a secondary reference antenna at least one antenna that is not within the first antenna array;
measuring at least a first signal propagation characteristic based on at least one signal wirelessly communicated between the primary reference antenna and the secondary reference antenna;
measuring at least a second signal propagation characteristic based on at least one signal wirelessly communicated between the secondary reference antenna and at least a second antenna within the first antenna array;
determining at least a first calibration coefficient for the second antenna within the first antenna array based on at least the first signal propagation characteristic and the second signal propagation characteristic; and
calibrating signal processing of the second antenna, the calibrating based on the first calibration coefficient.

Abstract
A method and a system for calibrating at least one antenna (1,1-1,3. 1,j). At least a first antenna (1,4) within a first antenna array (102) can be selected as a primary reference antenna. At least one antenna (4,3) that is not within the first antenna array can be selected as a secondary reference antenna. At least a first signal propagation characteristic (122) can be measured based on at least one signal wirelessly communicated between the primary reference antenna and the secondary reference antenna. At least a second signal propagation characteristic (118) can be measured based on at least one signal wirelessly communicated between the secondary reference antenna and at least a second antenna (1,2) within the first antenna array. At least a first calibration coefficient can be determined for the second antenna.
