This work proposes two topology design methods that account for channel and interference statistics: SER-DU (Seriation-Based DU Partitioning), which relies on spectral seriation, and FA-DU (Free Assignment-Based DU Partitioning), which performs unconstrained optimization of antenna elements into fixed-size clusters.
The simulation results reveal that the proposed HC-DA-UA framework always outperforms the existing counterparts in terms of sum-rate, whilst substantially decreasing the computational complexity and signalling overhead, thus it is an efficient and scalable solution for next-generation hardware-impaired distributed wire...

This article proposes an off-grid variational Bayesian channel-estimation framework for the considered distributed near-field MIMO geometry, which comprises equally spaced, collinear BS reference points and aligned uniform linear arrays (ULAs) with common inter-element spacing.
This paper proposes antenna selection-based beamforming optimization algorithms for full-duplex (FD) massive multiple-input multiple-output (mMIMO) large-scale arrays. The approach jointly selects the optimal transmit and receive antennas to optimize the propagation channels, thereby mitigating both self-interference (...
In this paper, we investigate the downlink performance of multi-cell RSMA-enabled ISAC networks in which base stations (BSs), communication users, and sensing targets are spatially distributed according to independent Poisson point processes (PPPs). Each BS simultaneously serves multiple users using RSMA while exploiti...

A unified family of Bayesian state filters based on concentrated Type-I and marginal Type-II likelihoods for wideband near-field D-MIMO systems are presented and it is shown that coherent processing substantially outperforms noncoherent processing.

This paper investigates the EE–SE trade-off in a downlink Massive MIMO system with Minimum Mean Square Error (MMSE) channel estimation (CE) and different linear combining and precoding techniques, confirming that MMSE-based CE provides higher spectral efficiency than the MR, ZF, RZF, and S-MMSE schemes, albeit at incre...
