Linear Massive MIMO Precoders in the Presence of Phase Noise -- A Large-Scale Analysis
R. Krishnan, M. R. Khanzadi, N. Krishnan +4
We study the impact of phase noise on the downlink performance of a multi-user multiple-input multiple-output system, where the base station (BS) employs a large number of transmit…
Coordinated Hybrid Automatic Repeat Request; Extended Version
Behrooz Makki, Tommy Svensson, Thomas Eriksson +1
We develop a coordinated hybrid automatic repeat request (HARQ) approach. With the proposed scheme, if a user message is correctly decoded in the first HARQ rounds, its spectrum is…
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…
Effect of Synchronizing Coordinated Base Stations on Phase Noise Estimation
M. Reza Khanzadi, Rajet Krishnan, Thomas Eriksson
In this paper, we study the problem of oscillator phase noise (PN) estimation in coordinated multi-point (CoMP) transmission systems. Specifically, we investigate the effect of pha…
Estimation of phase noise in oscillators with colored noise sources
M. Reza Khanzadi, Rajet Krishnan, Thomas Eriksson
In this letter we study the design of algorithms for estimation of phase noise (PN) with colored noise sources. A soft-input maximum a posteriori PN estimator and a modified soft-i…
On the Impact of Oscillator Phase Noise on the Uplink Performance in a Massive MIMO-OFDM System
Rajet Krishnan, M. Reza Khanzadi, N. Krishnan +4
In this work we study the effect of oscillator phase noise on the uplink performance of a massive multiple-input multiple output system. Specifically, we consider an orthogonal fre…
