On the Identifiability of Semi-Blind Estimation in Cell-Free Massive MIMO Networks
Christian Forsch, Laura Cottatellucci
Semi-blind joint channel estimation and data detection (JCD) is a promising approach to mitigate pilot contamination in cell-free massive multiple-input multiple-output (CF-MaMIMO)…
Expectation Propagation for Distributed Inference in Grant-Free Cell-Free Massive MIMO
Christian Forsch, Laura Cottatellucci
Grant-free cell-free massive multiple-input multiple-output (GF-CF-MaMIMO) systems are anticipated to be a key enabling technology for next-generation Internet-of-Things (IoT) netw…
Distributed Iterative ML and Message Passing for Grant-Free Cell-Free Massive MIMO Systems
Zilu Zhao, Christian Forsch, Laura Cottatellucci +1
Cell-Free (CF) Massive Multiple-Input Multiple-Output (MaMIMO) is considered one of the leading candidates for enabling next-generation wireless communication. With the growing int…
Bayesian Learning for Pilot Decontamination in Cell-Free Massive MIMO
Christian Forsch, Zilu Zhao, Dirk Slock +1
Pilot contamination (PC) arises when the pilot sequences assigned to user equipments (UEs) are not mutually orthogonal, eventually due to their reuse. In this work, we propose a no…
Wireless Information and Energy Transfer in the Era of 6G Communications
Constantinos Psomas, Konstantinos Ntougias, Nikita Shanin +8
Wireless information and energy transfer (WIET) represents an emerging paradigm which employs controllable transmission of radio-frequency signals for the dual purpose of data comm…
Distributed Joint User Activity Detection, Channel Estimation, and Data Detection via Expectation Propagation in Cell-Free Massive MIMO
Christian Forsch, Alexander Karataev, Laura Cottatellucci
We consider the uplink of a grant-free cell-free massive multiple-input multiple-output (GF-CF-MaMIMO) system. We propose an algorithm for distributed joint activity detection, cha…
