|Title:||Output-Controllable Partial Inverse Digital Predistortion for RF Power Amplifiers||Authors:||Yu, Chao; Allegue-Martínez, Michel; Guo, Yan; Zhu, Anding||Permanent link:||http://hdl.handle.net/10197/8416||Date:||2-Sep-2014||Online since:||2017-03-29T12:44:24Z||Abstract:||In this paper, an output-controllable digital predistortion (DPD) technique is proposed to partially inverse the nonlinear behavior of RF power amplifiers (PAs). Compared to the existing DPD, the proposed method changes the goal that the PA output must be exactly the same as the original input to a new one that the PA output can be arbitrarily controlled according to user's demand. The proposed approach largely expands the capability of DPD and thus provides more flexibility for system designers to effectively use DPD to manipulate the PA output in order to handle more application scenarios and objectively conduct further system optimization. Various application cases have been tested. The experimental results demonstrate that the proposed approach has great potential in future wireless communication system design.||Funding Details:||Science Foundation Ireland||Type of material:||Journal Article||Publisher:||IEEE||Journal:||IEEE Transactions on Microwave Theory and Techniques||Volume:||62||Issue:||11||Start page:||2499||End page:||2510||Copyright (published version):||2014 IEEE||Keywords:||Digital predistortion; Linearization; Multi-band; Output control; Power amplifiers; Wideband||DOI:||10.1109/TMTT.2014.2360175||Language:||en||Status of Item:||Peer reviewed|
