Symbol-Based Over-the-Air Digital Predistortion Using Reinforcement Learning
Yibo Wu, Jinxiang Song, Christian Häger +3
We propose an over-the-air digital predistortion optimization algorithm using reinforcement learning. Based on a symbol-based criterion, the algorithm minimizes the errors between…

Low Complexity Joint Impairment Mitigation of I/Q Modulator and PA Using Neural Networks
Yibo Wu, Ulf Gustavsson, Alexandre Graell i Amat +1
Neural networks (NNs) for multiple hardware impairments mitigation of a realistic direct conversion transmitter are impractical due to high computational complexity. We propose two…
