Optical wireless communications (OWCs) provide a promising alternative to spectrum‐congested microwave wireless communications. Recently, the use of metasurfaces with sub‐wavelength features for dynamic beam steering, beam manipulation, and spatial or optical‐angular‐momentum mode generation, conversion, and multiplexing in OWCs is proposed and ...

Multiple model predictive control for offshore wind turbines operating in the full‐load range
Abstract This paper presents a multiple model predictive control (MMPC) strategy based on an individual blade pitch (IBP) mechanism to control floating offshore wind turbines (FOWTs) when operating in the full‐load range (above the rated wind speed).

Modulation-mode assignment for SVD-assisted and iteratively detected downlink multiuser MIMO transmission schemes [PDF]
In this contribution we jointly optimize the number of multiple-input multiple-output (MIMO) layers and the number of bits per symbol within an iteratively-detected multiuser MIMO downlink (DL) transmission scheme under the constraint of a given fixed ...

We introduce a novel model of an IRS‐assisted MU‐MISO‐OFDMA system. We aim to jointly optimize beamforming vectors, IRS reflection coefficients, and OFDM subcarrier allocation to maximize the overall sum rate. ABSTRACT In this article, we propose a novel resource allocation strategy for multiuser multiple‐input single‐output orthogonal frequency ...

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.

MIMO Techniques and Applications [PDF]
First generation of cellular networks (1G) were analogue, having been deployed between 1980 and 1992. 1G included a myriad of cellular systems, namely the total access communication system (TACS), the advanced mobile phone system (AMPS), the Nordic mobile telephony (NMT), among others.
