Trade-Offs in Decentralized Gigantic MIMO with Hard-Boundary Constraints
Juan Vidal Alegría, Joao Vieira, Ove Edfors
To maintain the antenna apertures offered by 5G massive MIMO systems operating at the sub-6GHz band, known as FR1, 6G base stations (BSs) using the upper-mid band, FR3, should incr…
Achieving Distributed MIMO Performance with Repeater-Assisted Cellular Massive MIMO
Sara Willhammar, Hiroki Iimori, Joao Vieira +3
In what ways could cellular massive MIMO be improved? This technology has already been shown to bring huge performance gains. However, coverage holes and difficulties to transmit m…
Dynamic Range Improvement in Bistatic Backscatter Communication Using Distributed MIMO
Ahmet Kaplan, Joao Vieira, Erik G. Larsson
Backscatter communication (BSC) is a promising solution for Internet-of-Things (IoT) connections due to its low-complexity, low-cost, and energy-efficient solution for sensors. The…
Direct Link Interference Suppression for Bistatic Backscatter Communication in Distributed MIMO
Ahmet Kaplan, Joao Vieira, Erik G. Larsson
Backscatter communication (BC) is a promising technique for future Internet-of-Things (IoT) owing to its low complexity, low cost, and potential for energy-efficient operation in s…
Phase Calibration of Distributed Antenna Arrays
Erik G. Larsson, Joao Vieira
Antenna arrays can be either reciprocity calibrated (R-calibrated), which facilitates reciprocity-based beamforming, or fully calibrated (F-calibrated), which additionally facilita…
