Massive MIMO with Imperfect Channel Covariance Information
Emil Björnson, Luca Sanguinetti, Merouane Debbah
This work investigates the impact of imperfect statistical information in the uplink of massive MIMO systems. In particular, we first show why covariance information is needed and…
Design of 5G Full Dimension Massive MIMO Systems
Qurrat-Ul-Ain Nadeem, Abla Kammoun, Mérouane Debbah +1
Massive multiple-input-multiple-output (MIMO) transmission is a promising technology to improve the capacity and reliability of wireless systems. However, the number of antennas th…
Quantum Game Theory for Beam Alignment in Millimeter Wave Device-to-Device Communications
Qianqian Zhang, Walid Saad, Mehdi Bennis +1
In this paper, the problem of optimized beam alignment for wearable device-to-device (D2D) communications over millimeter wave (mmW) frequencies is studied. In particular, a noncoo…
Caching in the Sky: Proactive Deployment of Cache-Enabled Unmanned Aerial Vehicles for Optimized Quality-of-Experience
Mingzhe Chen, Mohammad Mozaffari, Walid Saad +3
In this paper, the problem of proactive deployment of cache-enabled unmanned aerial vehicles (UAVs) for optimizing the quality-of-experience (QoE) of wireless devices in a cloud ra…
Simultaneous Spectrum Sensing and Data Reception for Cognitive Spatial Multiplexing Distributed Systems
Nikolaos I. Miridakis, Theodoros A. Tsiftsis, George C. Alexandropoulos +1
A multi-user cognitive (secondary) radio system is considered, where the spatial multiplexing mode of operation is implemented amongst the nodes, under the presence of multiple pri…
A Multi-Service Oriented Multiple-Access Scheme For M2M Support in Future LTE
Nassar Ksairi, Stefano Tomasin, Mérouane Debbah
We propose a novel multiple-access technique to overcome the shortcomings of the current proposals for the future releases of Long-Term Evolution (LTE). We provide a unified radio…
