Energy-Efficient and Delay-Guaranteed Joint Resource Allocation and DU Selection in O-RAN
The radio access network (RAN) part of the next-generation wireless networks will require efficient solutions for satisfying low latency and high-throughput services. The open RAN (O-RAN) is one of the candidates to achieve this goal, in ad...
Prediction of HF Spectral Occupancy over Eastern Mediterranean Region Using Machine Learning
The ability of various machine learning (ML) algorithms to analyse and predict spectral occupancy in the high frequency (HF) spectrum is compared. One year of data (June 2012–June 2013) of HF spectral occupancy measurements collected by a ...
Data-driven and Model-driven Deep Learning Detection for RIS-aided Spatial Modulation
Reconfigurable intelligent surface (RIS) is regarded as a key technology for the next generation of wireless communications. Recently, the combination of RIS and spatial modulation (SM) or space shift keying (SSK) has attracted a lot of int...
Throughput Maximization & Power Optimization Analysis in Non-Orthogonal Multiple Access System
Currently, non-orthogonal multiple access (NOMA) has been considered as a key authorizing multiple access scheme for 5G & beyond (B5G) cellular systems. In NOMA, by utilizing the variations in channels gain, multiple users can be multiplexe...
Multi-Dimensional Modulation for Data Rate Maximization in Non-Orthogonal Spatial-Time-Frequency Domains
Loss of orthogonality among radio resource blocks in different domains introduces additional interference such as inter carrier interference (ICI) in frequency domain, and inter symbol interference (ISI) in time domain, and inter antenna co...
Dynamic Sectorization in Multi-Panel Massive MIMO Systems
In this paper, a multi-panel multiuser massive multiple-input multiple-output (MIMO) system is considered. Recently, it has been shown that the spectral efficiency in the massive MIMO downlink can be significantly improved by distributing t...
NVIDIA Aerial GPU Hosted AI-on-5G
In this paper we present the NVIDIA hyper-converged platform supporting 5G connectivity and Mobile Edge Computing (MEC). 5G connectivity is realized with our Aerial [1] GPU-based cloud native 5G gNB. We introduce AI-on-5G on a converged acc...
Channel-Aware Satisfactory Learning for Robust QoS Self-Provisioning in 5G and Beyond
Today’s services require a certain level of Quality of Service (QoS) to run smoothly and provide a satisfactory experience. Incongruously, most of the research efforts seek to maximize the perceived QoS whilst meeting a certain threshold w...
