International Journal of Satellite Communications and Networking, Volume 44, Issue 1, Page 17-33, January/February 2026.In this paper, we investigate the application of signal‐to‐leakage‐plus‐noise ratio (SLNR) beamforming to low Earth orbit non‐terrestrial networks. The SLNR criterion aims at maximizing the received desired signal power for each user while minimizing the overall interference power caused by each user to all other co‐channel receivers. We show that such

International Journal of Satellite Communications and Networking, Volume 44, Issue 1, Page 47-59, January/February 2026.The performance limitation in multiple‐input multiple‐output (MIMO) feeder links due to time and phase misalignment of the ground stations is investigated. Time and phase distribution over optical fiber is considered as an approach to achieve the synchronization requirements.

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.
