Abstract: The disclosure provides a transmitter of a communication system using hybrid digital/analog beamforming and configured to perform digital pre-distortion (DPD). In an exemplary embodiment in accordance with the disclosure, the transmitter may generate a plurality of scrambling sequences. The transmitter may comprise a plurality of combining modules to receive a combined feedback signal. The transmitter may use the plurality of scrambling sequences to recover the signals output by the antenna arrays from the combined feedback signal. Thus, the transmitter may perform DPD for each antenna array.
