Abstract
A method and an apparatus are provided for calibrating digital pre-distortion (DPD) of an electronic device. A respective signal is received, by each of a first plurality of receiving antennas, from each of a second plurality of transmitting antennas. A DPD function is determined for each of the second plurality of transmitting antennas based on the received signals. A combined DPD function of the second plurality of transmitting antennas is determined based on the DPD functions and phase shifter settings associated with the second plurality of transmitting antennas.
