| Title: | Pattern Sensing Based Digital Predistortion of RF Power Amplifiers under Dynamical Signal Transmission | Authors: | Yin, Hang; Yu, Chao; Lu, Qianyun; Zhu, Anding; et al. | Permanent link: | http://hdl.handle.net/10197/12072 | Date: | 16-Aug-2019 | Online since: | 2021-03-31T10:52:49Z | Abstract: | In this paper, a pattern sensing based digital predistortion (DPD) technique for radio frequency (RF) power amplifiers (PAs) under dynamical signal transmission is proposed. Unlike conventional methods where real time re-calibration is required, this approach utilizes a low resolution amplitude-modulation to amplitude-modulation (AM/AM) pattern to sense PA characteristics and then quickly select proper DPD coefficients to linearize the PA. Experimental results show that the proposed method can provide an efficient a nd effective w ay to deal with complex dynamic signal transmission scenarios and maintain very good linearization performance, which is very suitable for future 5G applications. | Funding Details: | Science Foundation Ireland | Funding Details: | National Natural Science Foundation of China | Type of material: | Conference Publication | Publisher: | IEEE | Copyright (published version): | 2019 IEEE | Keywords: | Sensors; Predistortion; Radio frequency; 5G mobile communication; Indexes; Table lookup; Real-time systems | DOI: | 10.1109/IMC-5G47857.2019.9160384 | Other versions: | http://imc-5g.mtt.org/ | Language: | en | Status of Item: | Peer reviewed | Is part of: | 2019 IEEE MTT-S International Microwave Conference on Hardware and Systems for 5G and Beyond (IMC-5G 2019) | Conference Details: | The 2019 IEEE MTT-S International Microwave Conference on Hardware and Systems for 5G and Beyond (IMC-5G), Atlanta, Georgia, United States of America, 15-16 August 2019 | ISBN: | 9781728131436 | This item is made available under a Creative Commons License: | https://creativecommons.org/licenses/by-nc-nd/3.0/ie/ |
