Opportunities for Intelligent Reflecting Surfaces in 6G-Empowered V2X Communications
Wali Ullah Khan, Asad Mahmood, Arash Bozorgchenani +7
This paper first describes the introduction of 6G-empowered V2X communications and IRS technology. Then it discusses different use case scenarios of IRS enabled V2X communications…
Backscatter-Aided NOMA V2X Communication under Channel Estimation Errors
Wali Ullah Khan, Muhammad Ali Jamshed, Asad Mahmood +3
Backscatter communications (BC) has emerged as a promising technology for providing low-powered transmissions in nextG (i.e., beyond 5G) wireless networks. The fundamental idea of…
When RIS Meets GEO Satellite Communications: A New Sustainable Optimization Framework in 6G
Wali Ullah Khan, Eva Lagunas, Asad Mahmood +2
Reflecting intelligent surfaces (RIS) is a low-cost and energy-efficient solution to achieve high spectral efficiency in sixth-generation (6G) networks. The basic idea of RIS is to…
Widely-distributed Radar Imaging Based on Consensus ADMM
Ruizhi Hu, Bhavani Shankar Mysore Rama Rao, Ahmed Murtada +2
A widely-distributed radar system is a promising architecture to enhance radar imaging performance. However, most existing algorithms rely on isotropic scattering assumption, which…
Multi-Antenna Data-Driven Eavesdropping Attacks and Symbol-Level Precoding Countermeasures
Abderrahmane Mayouche, Wallace A. Martins, Christos G. Tsinos +2
In this work, we consider secure communications in wireless multi-user (MU) multiple-input single-output (MISO) systems with channel coding in the presence of a multi-antenna eaves…
System Modelling and Design Aspects of Next Generation High Throughput Satellites
Shree Krishna Sharma, Jorge Querol, Nicola Maturo +2
Future generation wireless networks are targeting the convergence of fixed, mobile and broadcasting systems with the integration of satellite and terrestrial systems towards utiliz…
