Digital Post-Distortion Architectures for Nonlinear Power Amplifiers: Volterra and Kernel Methods
Daniel Schäufele, Jochen Fink, Renato L. G. Cavalcante +1
In modern 5G user equipments (UEs), the power amplifier (PA) contributes significantly to power consumption during uplink transmissions, especially in cell-edge scenarios. While re…
A joint channel estimation and beamforming separation principle for massive MIMO systems
Lorenzo Miretti, Slawomir Stańczak, Giuseppe Caire
We demonstrate that separating beamforming (i.e., downlink precoding and uplink combining) and channel estimation in multi-user MIMO wireless systems incurs no loss of optimality u…
CISSIR: Beam Codebooks with Self-Interference Reduction Guarantees for Integrated Sensing and Communication Beyond 5G
Rodrigo Hernangómez, Jochen Fink, Renato L. G. Cavalcante +1
We propose a beam codebook design for integrated sensing and communication (ISAC) that reduces self-interference (SI) to alleviate analog distortion. Our optimization framework, wh…
