An ESPRIT-Based Approach for 2-D Localization of Incoherently Distributed Sources in Massive MIMO Systems
Anzhong Hu, Tiejun Lv, Hui Gao +2
In this paper, an approach of estimating signal parameters via rotational invariance technique (ESPRIT) is proposed for two-dimensional (2-D) localization of incoherently distribut…
Aspects of Favorable Propagation in Massive MIMO
Hien Quoc Ngo, Erik G. Larsson, Thomas L. Marzetta
Favorable propagation, defined as mutual orthogonality among the vector-valued channels to the terminals, is one of the key properties of the radio channel that is exploited in Mas…
Matching theory for priority-based cell association in the downlink of wireless small cell networks
Omid Semiari, Walid Saad, Stefan Valentin +2
The deployment of small cells, overlaid on existing cellular infrastructure, is seen as a key feature in next-generation cellular systems. In this paper, the problem of user associ…
Optimal Design of Energy-Efficient Multi-User MIMO Systems: Is Massive MIMO the Answer?
Emil Björnson, Luca Sanguinetti, Jakob Hoydis +1
Assume that a multi-user multiple-input multiple-output (MIMO) system is designed from scratch to uniformly cover a given area with maximal energy efficiency (EE). What are the opt…
On the Average Performance of Caching and Coded Multicasting with Random Demands
Mingyue Ji, Antonia M. Tulino, Jaime Llorca +1
For a network with one sender, receivers (users) and possible messages (files), caching side information at the users allows to satisfy arbitrary simultaneous demands by se…
Caching and Coded Multicasting: Multiple Groupcast Index Coding
Mingyue Ji, Antonia M. Tulino, Jaime Llorca +1
The capacity of caching networks has received considerable attention in the past few years. A particularly studied setting is the case of a single server (e.g., a base station) and…
