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/|
