Energy-Delay Efficient Power Control in Wireless Networks
Alessio Zappone, Luca Sanguinetti, Merouane Debbah
This work aims at developing a power control framework to jointly optimize energy efficiency (measured in bit/Joule) and delay in wireless networks. A multi-objective approach is t…
Random Access in Massive MIMO by Exploiting Timing Offsets and Excess Antennas
Luca Sanguinetti, Antonio A. D'Amico, Michele Morelli +1
Massive MIMO systems, where base stations are equipped with hundreds of antennas, are an attractive way to handle the rapid growth of data traffic. As the number of user equipments…
Spectral and Energy Efficiency of Superimposed Pilots in Uplink Massive MIMO
Daniel Verenzuela, Emil Björnson, Luca Sanguinetti
Next generation wireless networks aim at providing substantial improvements in spectral efficiency (SE) and energy efficiency (EE). Massive MIMO has been proved to be a viable tech…
Network Deployment for Maximal Energy Efficiency in Uplink with Zero-Forcing
Andrea Pizzo, Daniel Verenzuela, Luca Sanguinetti +1
This work aims to design a cellular network for maximal energy efficiency (EE). In particular, we consider the uplink with multi-antenna base stations and assume that zero- forcing…
Large System Analysis of Power Normalization Techniques in Massive MIMO
Meysam Sadeghi, Luca Sanguinetti, Romain Couillet +1
Linear precoding has been widely studied in the context of Massive multiple-input-multiple-output (MIMO) together with two common power normalization techniques, namely, matrix nor…
Massive MIMO has Unlimited Capacity
Emil Björnson, Jakob Hoydis, Luca Sanguinetti
The capacity of cellular networks can be improved by the unprecedented array gain and spatial multiplexing offered by Massive MIMO. Since its inception, the coherent interference c…
Hybrid Precoding for Multi-Group Physical Layer Multicasting
Meysam Sadeghi, Luca Sanguinetti, Chau Yuen
Next generation of wireless networks will likely rely on large-scale antenna systems, either in the form of massive multi-input-multi-output (MIMO) or millimeter wave (mmWave) syst…
Optimal Design of Energy-Efficient Millimeter Wave Hybrid Transceivers for Wireless Backhaul
Andrea Pizzo, Luca Sanguinetti
This work analyzes a mmWave single-cell network, which comprises a macro base station (BS) and an overlaid tier of small-cell BSs using a wireless backhaul for data traffic. We loo…
Reducing the Computational Complexity of Multicasting in Large-Scale Antenna Systems
Meysam Sadeghi, Luca Sanguinetti, Romain Couillet +1
In this paper, we study the physical layer multicasting to multiple co-channel groups in large-scale antenna systems. The users within each group are interested in a common message…
