Adaptive Timers and Buffer Optimization for Layer-2 Protocols in 5G Non-Terrestrial Networks
Chandan Kumar Sheemar, Sumit Kumar, Jorge Querol +1
Interest in the integration of Terrestrial Networks (TN) and Non-Terrestrial Networks (NTN); primarily satellites; has been rekindled due to the potential of NTN to provide ubiquit…
IRS Assisted MIMO Full Duplex: Rate Analysis and Beamforming Under Imperfect CSI
Chandan Kumar Sheemar, Sourabh Solanki, Jorge Querol +2
Intelligent reflecting surfaces (IRS) have emerged as a promising technology to enhance the performance of wireless communication systems. By actively manipulating the wireless pro…
Robust Beamforming for IRS Aided MIMO Full Duplex Systems
Chandan Kumar Sheemar, Jorge Querol, Sourabh Solanki +2
In this paper, a novel robust beamforming for an intelligent reflecting surface (IRS) assisted FD system is presented. Since perfect channel state information (CSI) is often challe…
Architectures and Synchronization Techniques for Distributed Satellite Systems: A Survey
Liz Martinez Marrero, Juan C. Merlano Duncan, Jorge Querol +6
Cohesive Distributed Satellite Systems (CDSS) is a key enabling technology for the future of remote sensing and communication missions. However, they have to meet strict synchroniz…
Random Access Procedure over Non-Terrestrial Networks: From Theory to Practice
O. Kodheli, A. Astro, J. Querol +4
Non-terrestrial Networks (NTNs) have become an appealing concept over the last few years and they are foreseen as a cornerstone for the next generations of mobile communication sys…
Coexistence of Communications and Cognitive MIMO Radar: Waveform Design and Prototype
Mohammad Alaee-Kerahroodi, Ehsan Raei, Sumit Kumar +1
New generation of radar systems will need to coexist with other radio frequency (RF) systems, anticipating their behavior and reacting appropriately to avoid interference. In light…
