Digital Predistortion of Millimeter-Wave Multi-beam Transmitters with Digital Beam-forming Network
This paper proposes a novel digital predistortion (DPD) technique to linearize a millimeter-wave multi-beam transmitters with digital beam-forming network. It is achieved by modeling outputs of power amplifiers (PAs) and linearizing them with decomposed vector rotation-based model, respectively. The measurement results have shown that the proposed method can effectively realize the linearization of target beams, providing a promising solution for multi-user applications in 5G massive multiple-input multiple-output (mMIMO) wireless systems.
