Resource Allocation for Joint Communication and Localization Systems With MU-MIMO
Joint communication and localization is an attractive technique to simultaneously provide data transmission and localization services, and efficient resource allocation could bring a high data rate and high localization accuracy in limited resources ...

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

Guided exploration of user groups [PDF]
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]
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 ...
