Fuente: Wipo "digitalization" Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus may include first transceiver hardware comprising: first processing logic configured to generate a first plurality of output streams associated with a first sub-array of antenna elements of an antenna array by applying a first inverse power-amplifier- to-antenna-array network (A-l) matrix to one or more first input streams; and a first plurality of digital predistortion (DPD) circuits that are apply first DPD to the first plurality of output streams. The apparatus may include second transceiver hardware comprising: second processing logic configured to generate a second plurality of output streams associated with a second sub-array of antenna elements of the antenna array by applying a second A-l matrix to second one or more input streams, and a second plurality of DPD circuits configured to apply second DPD to the second plurality of output streams.
