5G massive MIMO architectures: self-backhauled small cells versus direct access

Bonfante, Andrea; Galati Giordano, Lorenzo; López Pérez, David; García Rodríguez, Adrián; Geraci, Giovanni; Baracca, Paolo; Butt, Majid; Marchetti, Nicola (Institute of Electrical and Electronics Engineers (IEEE), 2019)

In this paper, we focus on one of the key technologies for the fifth-generation wireless communication networks, massive multiple-input-multiple-output (mMIMO), by investigating two of its most relevant architectures: ...
Analytical handle for ZF reception in distributed massive MIMO

Senanayake, Rajitha; Lozano Solsona, Angel; Smith, Peter; Evans, Jamie (Institute of Electrical and Electronics Engineers (IEEE), 2016)

This paper considers distributed massive MIMO networks where a large number of antennas, either collocated or geographically scattered over a region, communicate with mobile users. This communication is impaired by ...
Channel estimation and hybrid combining for wideband terahertz massive MIMO systems

Dovelos, Konstantinos; Matthaiou, Michail; Ngo, Hien Quoc; Bellalta, Boris (Institute of Electrical and Electronics Engineers (IEEE), 2021)

Terahertz (THz) communication is widely considered as a key enabler for future 6G wireless systems. However, THz links are subject to high propagation losses and inter-symbol interference due to the frequency selectivity ...
Modified conjugate beamforming for cell-free massive MIMO

Attarifar, Masoud; Abbasfar, Aliazam; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2019)

We present a modification of conjugate beamforming for the forward link of cell-free massive MIMO networks. This modification eliminates the self-interference and yields a performance that, without forward pilots, closely ...
Understanding UAV cellular communications: from existing networks to massive MIMO

Geraci, Giovanni; García Rodríguez, Adrián; Galati Giordano, Lorenzo; López Pérez, David; Björnson, Emil (Institute of Electrical and Electronics Engineers (IEEE), 2018)

The purpose of this article is to bestow the reader with a timely study of UAV cellular communications, bridging the gap between the 3GPP standardization status quo and the more forward-looking research. Special emphasis ...
What will 5G be?

Andrews, Jeffrey G.; Buzzi, Stefano; Choi, Wan; Hanly, Stephen; Lozano Solsona, Angel; Soong, Anthony C.K.; Zhang, Jianzhong Charlie (Institute of Electrical and Electronics Engineers (IEEE), 2014)

What will 5G be? What it will not be is an incremental/nadvance on 4G. The previous four generations of/ncellular technology have each been a major paradigm shift/nthat has broken backwards compatibility. And indeed, 5G ...
