Multipair Full-Duplex Relaying With Massive Arrays and Linear Processing
TLDR
We consider a multipair decode-and-forward relay channel, where multiple sources transmit simultaneously their signals to multiple destinations with the help of a full-duplex relay station. Expand

Power Scaling of Uplink Massive MIMO Systems With Arbitrary-Rank Channel Means
TLDR
This paper investigates the uplink achievable rates of massive multiple-input multiple-output (MIMO) antenna systems in Ricean fading channels, using maximal-ratio combining (MRC) and zero-forcing (ZF) receivers, assuming perfect and imperfect channel state information. Expand

A New Look at Dual-Hop Relaying: Performance Limits with Hardware Impairments
TLDR
We derive new closed-form expressions for the exact and asymptotic OPs, accounting for hardware impairments at the source, relay, and destination. Expand

Massive MIMO with Non-Ideal Arbitrary Arrays: Hardware Scaling Laws and Circuit-Aware Design
TLDR
Massive multiple-input multiple-output (MIMO) systems are cellular networks where the base stations (BSs) are equipped with unconventionally many antennas. Expand

On the Total Energy Efficiency of Cell-Free Massive MIMO
TLDR
We consider the cell-free massive multiple-input multiple-output (MIMO) downlink, where a very large number of distributed multiple-Antenna access points (APs) serve many single-antenna users in the same time-frequency resource. Expand

Beam Division Multiple Access Transmission for Massive MIMO Communications
TLDR
We study multicarrier multiuser multiple-input multiple-output (MU-MIMO) systems, in which the base station employs an asymptotically large number of antennas, and propose a beam division multiple access (BDMA) transmission scheme that simultaneously serves multiple users via different beams.

Diversity Combining in Hybrid RF/FSO Systems with PSK Modulation
TLDR
We present a novel architecture for hybrid radio frequency (RF)/ free space optical (FSO) wireless systems without feedback or channel state information (CSI) at the transmitter. Expand

Sum Rate Analysis of ZF Receivers in Distributed MIMO Systems
TLDR
The performance of single-cell distributed multiple-input multiple-output (D-MIMO) systems is not only affected by small-scale Rayleigh fading but also from large-scale fading and path-loss. Expand
