Thresholds Optimization of Decomposed Vector Rotation Model for Digital Predistortion of RF Power Amplifier [PDF]
Radioengineering, 2021 In this paper, we propose an efficient approach for optimizing the decomposed vector rotation (DVR) model for digital predistortion (DPD). The DVR model’s basis functions are constructed piecewise by dividing the input space into segments bounded by ...

Power Quality Improvement Using DVR [PDF]
American Journal of Applied Sciences, 2009 Voltage sags and swells in the medium and low voltage distribution grid are considered to be the most frequent type of power quality problems based on recent power quality studies. Their impact on sensitive loads is severe. The impact ranges from load disruptions to substantial economic losses up to millions of dollars.
