Mobile near-field terahertz communications for 6G and 7G networks: Research challenges

Publication Type: Academic Journal

Source(s): Frontiers in Communications and Networks, Vol 4 (2023)

Abstract: Following the current development of the wireless technology landscape, and with respect to the constant growth in user demands, it is inevitable that next-generation mobile wireless networks will use new frequency bands located in the sub-terahertz an...


Publication Type: Academic Journal

Source(s): Acta Medica Leopoliensia, Vol 27, Iss 3-4, Pp 59-67 (2021)

Abstract: Aim. Renal cancer complicated by renal vein thrombosis spreading to the supradiaphragmatic inferior vena cava poses an increased risk of treatment due to the likelihood of pulmonary embolism by thrombotic masses. Issues of surgical access and technique...

Quasi-Orthogonal Space-Time Block Coding with Closed-Loop Control in MIMO Communication Systems

Publication Type: Academic Journal

Source(s): Proceedings of the XXth Conference of Open Innovations Association FRUCT, Vol 29, Iss 1, Pp 30-35 (2021)

Abstract: In the paper, we proposed a method of space-time diversity on the transmitting side, combining a closed feedback and quasi-orthogonal space-time coding technique called closed-loop control with quasi-orthogonal space-time block coding (QO-STBC). For a ...

First Trifluoromethylated Phenanthrolinediamides: Synthesis, Structure, Stereodynamics and Complexation with Ln(III)

Publication Type: Academic Journal

Source(s): Molecules, Vol 27, Iss 3114, p 3114 (2022)

Abstract: The first examples of 1,10-phenanthroline-2,9-diamides bearing CF3-groups on the side amide substituents were synthesized. Due to stereoisomerism and amide rotation, such complexes have complicated behavior in solutions. Using advanced NMR techniques a...

First Example of Fluorinated Phenanthroline Diamides: Synthesis, Structural Study, and Complexation with Lanthanoids

Publication Type: Academic Journal

Source(s): Molecules, Vol 27, Iss 4705, p 4705 (2022)

Abstract: An efficient approach to the synthesis of diamides of 4,7-difluoro-1,10-phenanthroline-2,9-dicarboxylic acid was elaborated. Direct nucleophilic substitution with 4,7-dichloro-1,10-phenanthroline precursors opened access to difluoro derivatives in high...

Equivalent MIMO Channel Matrix Sparsification for Enhancement of Sensor Capabilities

Publication Type: Academic Journal

Source(s): Sensors, Vol 22, Iss 2041, p 2041 (2022)

Abstract: One of the development directions of new-generation mobile communications is using multiple-input multiple-output (MIMO) channels with a large number of antennas. This requires the development and utilization of new approaches to signal detection in MI...

Session-Level Reliability Analysis for Multi-Service Communication in Autonomous Vehicular Fleets

Publication Type: Academic Journal

Source(s): IEEE Access, Vol 8, Pp 174629-174642 (2020)

Abstract: The support for reliable communication in the increasingly large fleets of autonomous vehicles is one of the important challenges for emerging 5G systems. The presence of heterogeneous data streams of different priority between the connected vehicles (...

Detection of Low-Energy X-rays Using YSO Scintillation Crystal Arrays for GRB Experiments

Publication Type: Academic Journal

Source(s): Universe, Vol 7, Iss 396, p 396 (2021)

Abstract: We developed an X-ray detector using 36 arrays, each consisting of a 64-pixellated yttrium oxyorthosilicate (YSO) scintillation crystal and a 64-channel multi-anode photomultiplier tube. The X-ray detector was designed to detect X-rays with energies lo...

A New Algorithm of Iterative MIMO Detection and Decoding Using Linear Detector and Enhanced Turbo Procedure in Iterative Loop

Publication Type: Academic Journal

Source(s): Proceedings of the XXth Conference of Open Innovations Association FRUCT, Vol 854, Iss 24, Pp 40-46 (2019)

Abstract: In the paper we develop and evaluate a novel low complexity algorithm of iterative detection and decoding in multiple input multiple output (MIMO) system. It is based on a new enhanced Turbo procedure. Although the algorithm utilizes well-known compone...

Integrated Use of Licensed- and Unlicensed-Band mmWave Radio Technology in 5G and Beyond

Publication Type: Academic Journal

Source(s): IEEE Access, Vol 7, Pp 24376-24391 (2019)

Abstract: The 3GPP standardization rapidly moves forward with studies of a wide-bandwidth waveform as well as an adaptation of the emerging 5G new radio (NR)-based access to the unlicensed spectrum (NR-U). One of the basic architectures for NR-U involves carrier...
