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…
Investigation of Parameter Adaptation in RF Power Amplifier Behavioral Models
Ali Soltani Tehrani, Jessica Chani, Thomas Eriksson +1
This paper presents an investigation into parameter adaptation in behavioral model--based digital predistortion for radio frequency power amplifiers. A novel measurement setup fram…
Black-box Modeling and Compensation of Bursty Communication Signals in RF Power Amplifiers with Power-Dependent Parameters
Ali Soltani Tehrani, Haiying Cao, Thomas Eriksson +1
This paper presents a new black-box technique for modeling long term memory effects in radio frequency power amplifiers. The proposed technique extends commonly used behavioral mod…
Capacity of SIMO and MISO Phase-Noise Channels with Common/Separate Oscillators
M. Reza Khanzadi, Giuseppe Durisi, Thomas Eriksson
In multiple antenna systems, phase noise due to instabilities of the radio-frequency (RF) oscillators, acts differently depending on whether the RF circuitries connected to each an…
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…
