User behaviour-driven group formation through case-based reasoning and clustering [PDF]

open access: yes, 2012
Group formation for collaborative learning activities is a complex and time consuming task. Different criteria have been proposed for grouping learners in computer-based systems, such as performance and social characteristics. User behaviour is, however,

Beam interference suppression in multi-cell millimeter wave communications

open access: yesDigital Communications and Networks, 2019
Due to the increase in the number of users, beam switching is used for suppressing interference, which leads to higher computational complexity in multi-cell millimeter wave communications.

Joint User Grouping and Decoding Order in Uplink/Downlink MISO/SIMO-NOMA

open access: yesIEEE Access, 2020
In this paper, we design and investigate a novel uplink/downlink (UL/DL) non-orthogonal multiple access (NOMA) network using a common relay. Instead of successive interference cancellation (SIC) for UL/DL NOMA systems with fixed decoding order based on ...

User Selection and Resource Allocation Algorithms for Multicarrier NOMA Systems on Downlink Beamforming

open access: yesIEEE Access, 2020
In this paper, we propose user grouping, subcarrier allocation, and bit allocation schemes in multicarrier nonorthogonal multiple access (NOMA) systems on downlink beamforming to reduce the total transmit power while considering the data-rate and the ...

Cell-Free Massive MIMO System With an Adaptive Switching Algorithm Between Cooperative NOMA, Non-Cooperative NOMA, and OMA Modes

open access: yesIEEE Access, 2021
Non-orthogonal multiple access (NOMA) aided cell-free massive multiple-input multiple-output (CF mMIMO) systems have gained great attention over the past few years to be employed in the sixth generation of the wireless network.

Guided exploration of user groups [PDF]

open access: yesProceedings of the VLDB Endowment, 2020
Finding a set of users of interest serves several applications in behavioral analytics. Often times, identifying users requires to explore the data and gradually choose potential targets. This is a special case of Exploratory Data Analysis (EDA), an iterative and tedious process.

performance analysis and optimal user grouping [PDF]

open access: yes, 2017
We explore the performance of N-user multi-point-to-multi-point Free Space Optical (FSO) communication systems. For such systems, the communication between the N transmitters and N receivers relies on user grouping for the sake of achieving enhanced ...
