This abstract first appeared for US patent application 20240429954 titled 'DIGITAL PRE-DISTORTION FOR BEAMFORMING TRANSCEIVERS
Original Abstract Submitted
according to some embodiments, in a radio frequency (rf) transceiver system having a transmit chain with a beamforming array, a digital pre-distorter (dpd) includes: a plurality of inputs including at least a first input to receive a first signal corresponding to a signal desired to be transmitted via the transmit chain or a modified version of the signal desired to be transmitted via the transmit chain, and a second input to receive a second signal corresponding to a signal associated with the beamforming array or a translated version of the signal associated with the beamforming array; circuitry configured to apply digital predistortion to the signal desired to be transmitted based at least in part on combining the first and second signals; and an output connected to provide a resulting pre-distorted signal to the transmit chain.
