A method, apparatus and system for performing over-the-air calibration routines in a multiple-input multiple-output (MIMO) communication system. An antenna array of a transceiver (e.g., transceiver of a base station) comprises a re-configurable antenna having two switchable configuration states. The antenna exhibits different degrees of electromagnetic coupling to other antennas of the array in a first state than in a second state. The reference antenna is switched to the first state for performing uplink/downlink calibrating transmissions and switched to the second state during uplink and downlink communications or channel sounding calibrating transmissions.
