Claim 9:
10. The MIMO transmitter of claim 8 wherein, in order to determine the desired input signal, Ul, for a respective one of the plurality of antenna branches, each ILC DPD system of the plurality of ILC DPD systems is further operable to:
initialize the desired input signal, Ul, for the respective one of the plurality of antenna branches;
iteratively perform the following until at least one predefined criterion is satisfied:
determine an error, El, based on a difference between (a) a desired output signal of the respective one of the plurality of antenna branches and (b) an actual output signal of the respective one of the plurality of antenna branches when the desired input signal, Ul, is applied to the respective one of the plurality of antenna branches;
update the desired input signal, Ul, for the respective one of the plurality of antenna branches based on the error, El.
