Digital Post-Distortion for Joint Mitigation of Transmitter I/Q Imbalance and Power Amplifier Nonlinearities in Multiuser MIMO Networks

In this paper, we propose a novel digital post-distortion (DPoD) technique designed to improve the received signal quality in orthogonal frequency-division multiple (OFDM)-based multi-user multiple-input multiple-output (MU-MIMO) systems suffering from severe coexisting transmitter impairments in the form of power ampl...

Has The Physical Layer Matured?

The PHY layer is therefore not dead; its most consequential advances will come from deployable spatial processing and CSI acquisition, complemented by targeted link-level and AI/ML-based refinements.
