Impact of Spatial Filtering on Distortion from Low-Noise Amplifiers in Massive MIMO Base Stations
Christopher Mollén, Ulf Gustavsson, Thomas Eriksson +1
In massive MIMO base stations, power consumption and cost of the low-noise amplifiers (LNAs) can be substantial because of the many antennas. We investigate the feasibility of inex…
Spatial Characteristics of Distortion Radiated from Antenna Arrays with Transceiver Nonlinearities
Christopher Mollén, Ulf Gustavsson, Thomas Eriksson +1
The distortion from massive MIMO (multiple-input--multiple-output) base stations with nonlinear amplifiers is studied and its radiation pattern is derived. The distortion is analyz…
Impact of Major RF Impairments on mm-wave Communications using OFDM Waveforms
Yaning Zou, Per Zetterberg, Ulf Gustavsson +5
In this paper, we study the joint impact of three major RF im-pairments, namely, oscillator phase noise, power amplifier non-linearity and I/Q imbalance on the performance of a mm-…
