| Title: | Real-Time Single Channel Over-the-Air Data Acquisition for Digital Predistortion of 5G Massive MIMO Wireless Transmitters | Authors: | Wang, Xiaoyu; Yu, Chao; Li, Yue; Hong, Wei; Zhu, Anding | Permanent link: | http://hdl.handle.net/10197/11050 | Date: | 22-May-2019 | Online since: | 2019-08-29T08:19:38Z | Abstract: | In this paper, a single channel over-the-air (OTA) data acquisition approach for real-time calibration of digital predistorter in multiple-input multiple-output transmitters is proposed. By using the data acquired from the far-field OTA tests, the output of each power amplifier (PA) can be virtually reconstructed and thus the linearization reference at the main beam direction can be accurately estimated. Digital predistortion (DPD) can therefore be effectively constructed without direct measurement at PA output. Experimental results demonstrate that the proposed scheme can accurately estimate far-field main beam data and the proposed DPD can achieve excellent linearization performance. | Funding Details: | Science Foundation Ireland | Type of material: | Conference Publication | Publisher: | IEEE | Copyright (published version): | 2019 IEEE | Keywords: | 5G; Beam-forming; Over-the-air; Digital predistortion; Multiple-input multiple-output; Millimeter wave; Power amplifier | DOI: | 10.1109/ieee-iws.2019.8804102 6186113600 |
