International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT In privacy protection of control systems, a trade‐off between control performance and privacy level is often pointed out. Our goal in this paper is to improve this trade‐off by shaping the frequency of noise added for privacy protection when the control objective is to track a reference signal, which is taken as a piece of information whose ...

Dual-Polarized Ricean MIMO Channels: Modeling and Performance Assessment
, 2012 In wireless communication systems, dual-polarized (DP) instead of single-polarized (SP) multiple-input multiple-output (MIMO) transmission is used to improve the spectral efficiency under certain conditions on the channel and the signal-to-noise ratio ...

Location‐Assisted Graph‐Based User Scheduling in Multi‐User MIMO LEO NTN Systems
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT This paper addresses user clustering and scheduling for multi‐user MIMO low Earth orbit nonterrestrial network systems in full frequency reuse. Since the number of on‐ground user terminals is usually much higher than the number of on‐board LEO satellite antennas, user scheduling becomes a fundamental task.

Millimetre wave 3-D channel modelling for next generation 5G networks
AIMS Electronics and Electrical Engineering, 2022 Millimetre wave (mm-wave) spectrum (30-300GHz) is a key enabling technology in the advent of 5G. However, an accurate model for the mm-wave channel is yet to be developed as the existing 4G-LTE channel models (frequency below 6 GHz) exhibit different ...

2017 IEEE 18th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2017 In this paper, we consider the use of deep neural networks in the context of Multiple-Input-Multiple-Output (MIMO) detection. We give a brief introduction to deep learning and propose a modern neural network architecture suitable for this detection task.

Spatial Coding Techniques for Molecular MIMO
, 2017 This paper studies spatial diversity techniques applied to multiple-input multiple-output (MIMO) diffusion-based molecular communications (DBMC). Two types of spatial coding techniques, namely Alamouti-type coding and repetition MIMO coding are suggested

Facilitating Sodium‐Ion Diffusion in Fe‐Doped Co3O4 for High‐Rate Performance
Small, EarlyView.The limited rate performance of cobalt oxide (Co3O4) materials restricts their applicability in the rapid charge–discharge process of sodium‐ion batteries (SIBs). Iron (Fe) lattice doping can facilitate sodium‐ion diffusion by narrowing the bandgap and modulating the Co─O bond length.
