Reconfigurable Intelligent Surfaces: Three Myths and Two Critical Questions
Emil Björnson, Özgecan Özdogan, Erik G. Larsson
The search for physical-layer technologies that can play a key role in beyond-5G systems has started. One option is reconfigurable intelligent surfaces (RIS), which can collect wir…
Performance of Cell-Free Massive MIMO with Rician Fading and Phase Shifts
Özgecan Özdogan, Emil Björnson, Jiayi Zhang
In this paper, we study the uplink (UL) and downlink (DL) spectral efficiency (SE) of a cell-free massive multiple-input-multiple-output (MIMO) system with Rician fading channels.…
Uplink Spectral Efficiency of Massive MIMO with Spatially Correlated Rician Fading
Özgecan Özdogan, Emil Björnson, Erik G. Larsson
This paper considers the uplink (UL) of a multi-cell Massive MIMO (multiple-input multiple-output) system with spatially correlated Rician fading channels. The channel model is com…
Massive MIMO with Spatially Correlated Rician Fading Channels
Özgecan Özdogan, Emil Björnson, Erik G. Larsson
This paper considers multi-cell Massive MIMO (multiple-input multiple-output) systems where the channels are spatially correlated Rician fading. The channel model is composed of a…
