Abstract

An approach to predistortion of a first set of signals for an antenna array allows beam-steering without corrupting spectrum away from the main beam and where other users may be located. In some implementations, the predistorter uses fewer than one predistorter per signal (i.e., per power amplifier or per antenna), and/or has the computational complexity of such fewer predistorters, to generate predistortions of the first set of signals for amplification and transmission via the antenna array.
