논문 초록 (Abstract)
This paper proposes a digital pre-distortion (DPD) technique for analog beamforming systems. The considering system has M PAs (M is the number of antennas) and one digital chain. In contrast to the conventional DPD problem where one DPD linearizes one PA, a single DPD should linearize M PAs simultaneously in the analog beamforming system. In this paper, we design a new DPD by minimizing the sum of linearization errors of M PAs. To verify the proposed DPD, computer simulation and experiment are conducted. The results confirm that the proposed DPD can successfully linearize the multiple PAs in analog beamforming systems.
