Abstract:
A method for a transceiver calibration and antenna array operation in a multi-input multi-output (MIMO) system. The method comprises sending a calibration signal and a pre-designed training sequence, via a coupling network, receiving a calibration signal and a pre-designed training sequence that is sent a the transceiver array in a time slotted pattern via a coupling network, generating an Rx calibration measurement (R 1 ) based on one or more uplink signals received via antenna array and the coupling network, generating a Tx calibration measurement (T 1 ) based on receipt of the calibration signal from each of antennas via the coupling network; and performing a joint Tx/Rx (TRx) calibration based on HR, R 1 , and T 1 , where H is a channel response in air interface, R is a channel response of receivers in transceiver array.

Claim (Index 13):
The method of  claim 12 , wherein the R 1  comprises a product of the channel response of the receivers in the transceiver array (R) and a channel response of the coupling network (Ec), and wherein the T 1  comprises a product of a channel response of transmitters in the transceiver array (T) and the channel response of the coupling network (Ec).
