Distortion-Aware Linear Precoding for Massive MIMO Downlink Systems with Nonlinear Power Amplifiers
Sina Rezaei Aghdam, Sven Jacobsson, Ulf Gustavsson +3
We introduce a framework for linear precoder design over a massive multiple-input multiple-output downlink system in the presence of nonlinear power amplifiers (PAs). By studying t…

Residual Neural Networks for Digital Predistortion
Yibo Wu, Ulf Gustavsson, Alexandre Graell i Amat +1
Tracking the nonlinear behavior of an RF power amplifier (PA) is challenging. To tackle this problem, we build a connection between residual learning and the PA nonlinearity, and p…
