An Orthogonal Approximate Message Passing Framework for Multiuser Communications
Burak Çakmak, Hao Yan, Alexander Fengler +2
We solve the open problem of constructing a Bayes-optimal iterative signal recovery algorithm for linear-Gaussian \emph{multiuser} communication systems with random precoding at th…
Optimal Communication Rate of Secure Aggregation over Ring Networks with Pairwise Keys
Xiang Zhang, Han Yu, Zhou Li +2
Information-theoretic topological secure aggregation (TSA)\cite{zhang2026information_regular} enables distributed users to compute neighborhood sums over arbitrary networks without…
Reducing Subpacketization in Device-to-Device Coded Caching via Heterogeneous File Splitting
Xiang Zhang, Giuseppe Caire, Mingyue Ji
The packet type (PT)-based framework~\cite{zhang2026taming} provides a systematic and principled approach to designing device-to-device (D2D) coded caching schemes that achieve red…
On the Fundamental Limits of Hierarchical Secure Aggregation with Dropout and Collusion Resilience
Zhou Li, Yizhou Zhao, Xiang Zhang +1
We study the fundamental communication limits of information-theoretic secure aggregation in a hierarchical network consisting of a server, multiple relays, and multiple users per…
Channel Estimation under Large Doppler Shifts and Channel Aging in NOMA-Based Air-Ground Communications
Ayten Gürbüz, Giuseppe Caire, Michael Walter
This paper investigates a multiple antenna system with non-orthogonal multiple access (NOMA) for the exchange of air traffic management data between commercial aircraft pilots and…
Joint Message Detection, Channel, and User Position Estimation for Unsourced Random Access in Cell-Free Networks
Eleni Gkiouzepi, Burak Çakmak, Manfred Opper +1
We consider unsourced random access (uRA) in user-centric cell-free (CF) wireless networks, where random access users send codewords from a common codebook during specifically dedi…
