Enabling NLoS LEO Satellite Communications with Reconfigurable Intelligent Surfaces
Xiaowen Tian, Nuria Gonzalez-Prelcic, Takayuki Shimizu
Low Earth Orbit (LEO) satellite communications (SatCom) are considered a promising solution to provide uninterrupted services in cellular networks. Line-of-sight (LoS) links betwee…
Optimizing the Deployment of Reconfigurable Intelligent Surfaces in MmWave Vehicular Systems
Xiaowen Tian, Nuria Gonzalez-Prelcic, Robert W. Heath
Millimeter wave (MmWave) systems are vulnerable to blockages, which cause signal drop and link outage. One solution is to deploy reconfigurable intelligent surfaces (RISs) to add a…
5G MIMO Data for Machine Learning: Application to Beam-Selection using Deep Learning
Aldebaro Klautau, Pedro Batista, Nuria Gonzalez-Prelcic +2
The increasing complexity of configuring cellular networks suggests that machine learning (ML) can effectively improve 5G technologies. Deep learning has proven successful in ML ta…
