Optimal Pilot and Payload Power Control in Single-Cell Massive MIMO Systems
Hei Victor Cheng, Emil Björnson, Erik G. Larsson
This paper considers the jointly optimal pilot and data power allocation in single-cell uplink massive multiple-input-multiple-output (MIMO) systems. Using the spectral efficiency…
Achievable Uplink Rates for Massive MIMO with Coarse Quantization
Christopher Mollén, Junil Choi, Erik G. Larsson +1
The high hardware complexity of a massive MIMO base station, which requires hundreds of radio chains, makes it challenging to build commercially. One way to reduce the hardware com…
Spatio-Temporal Waveform Design for Multi-user Massive MIMO Downlink with 1-bit Receivers
Ahmet Gokceoglu, Emil Bjornson, Erik Larsson +1
Internet-of-Things (IoT) refers to a high-density network of low-cost low-bitrate terminals and sensors where also low energy consumption is one central feature. As the power-budge…
Out-of-Band Radiation from Large Antenna Arrays
Christopher Mollén, Erik G. Larsson, Ulf Gustavsson +2
Co-existing wireless systems, which share a common spectrum, need to mitigate out-of-band (OOB) radiation to avoid excessive interference. For legacy systems, OOB radiation is well…
On the Performance of Cell-Free Massive MIMO with Short-Term Power Constraints
Giovanni Interdonato, Hien Quoc Ngo, Erik G. Larsson +1
In this paper we consider a time-division duplex cell-free massive multiple-input multiple-output (MIMO) system where many distributed access points (APs) simultaneously serve many…
Multi-Cell Massive MIMO Performance with Double Scattering Channels
Trinh Van Chien, Emil Björnson, Erik G. Larsson
This paper investigates the spectral efficiency (SE) of multi-cell Massive Multi-Input Multi-Output (MIMO) using different channel models. Prior works have derived closed-form SE b…
