Claim 16:
17. The MIMO transmitter of claim 16 wherein, in order to determine the desired combined input signal, U, for the plurality of antenna branches, the single DPD system is further operable to:
initialize the desired combined input signal, U, for the plurality of antenna branches;
iteratively perform the following until at least one predefined criterion is satisfied:
determine an error, E, based on: (a) a difference between a desired combined output signal of the plurality of antenna branches and (b) an actual combined output signal of the plurality of antenna branches when the desired combined input signal, U, is applied to the plurality of antenna branches; and
update the desired combined input signal, U, for the plurality of antenna branches based on the error, E.
