On the Impact of Hardware Impairments on Massive MIMO
Ulf Gustavsson, Cesar Sanchéz-Perez, Thomas Eriksson +6
Massive multi-user (MU) multiple-input multiple-output (MIMO) systems are one possible key technology for next generation wireless communication systems. Claims have been made that…
A Parameterized Base Station Power Model
Hauke Holtkamp, Gunther Auer, Vito Giannini +1
Power models are needed to assess the power consumption of cellular Base Station (BS) on an abstract level. Currently available models are either too simplified to cover necessary…
Asymptotic Performance Analysis of a K-Hop Amplify-and-Forward Relay MIMO Channel
Maksym A. Girnyk, Mikko Vehkaperä, Lars K. Rasmussen
The present paper studies the asymptotic performance of multi-hop amplify-and-forward relay multiple-antenna communication channels. Each multi-antenna terminal in the network ampl…
On the MIMO Capacity with Residual Transceiver Hardware Impairments
Xinlin Zhang, Michail Matthaiou, Emil Björnson +2
Radio-frequency (RF) impairments in the transceiver hardware of communication systems (e.g., phase noise (PN), high power amplifier (HPA) nonlinearities, or in-phase/quadrature-pha…
Design and Analysis of a Greedy Pursuit for Distributed Compressed Sensing
Dennis Sundman, Saikat Chatterjee, Mikael Skoglund
We consider a distributed compressed sensing scenario where many sensors measure correlated sparse signals and the sensors are connected through a network. Correlation between spar…
