5G new radio multiuser precoding in geostationary satellite networks
International Journal of Satellite Communications and Networking, Volume 44, Issue 1, Page 60-72, January/February 2026.This work evaluates the standardized 5G new radio codebooks for closed‐loop multiuser precoding in GEO multibeam scenarios and derives a list of recommended 3GPP standard modifications for a proper support to GEO mission needs. Summary The multiuser precoding procedures standardized by the 3rd Generation Partnership Project (3GPP) for new radio (NR ...

Data‐Driven Sliding Mode Control for Partially Unknown Nonlinear Systems
International Journal of Robust and Nonlinear Control, Volume 36, Issue 2, Page 629-638, 25 January 2026.ABSTRACT This paper presents a novel data‐driven control framework for multi‐input multi‐output (MIMO) nonlinear systems with partially unknown dynamics and bounded disturbances. In practical scenarios, exact cancellation of system nonlinearities is often infeasible due to limited model information and unpredictable disturbances.

Diffusive MIMO Molecular Communications: Channel Estimation, Equalization and Detection
, 2019 In diffusion-based communication, as for molecular systems, the achievable data rate is low due to the stochastic nature of diffusion which exhibits a severe inter-symbol-interference (ISI). Multiple-Input Multiple-Output (MIMO) multiplexing improves the

Active Sampling of Interpolation Points to Identify Dominant Subspaces for Model Reduction
International Journal for Numerical Methods in Engineering, Volume 127, Issue 1, 15 January 2026.ABSTRACT Model reduction is an active research field to construct low‐dimensional surrogate models of high fidelity to accelerate engineering design cycles. In this work, we investigate model reduction for linear structured systems using dominant reachable and observable subspaces.
