Massive Machine Type Communication Pilot-Hopping Sequence Detection Architectures Based on Non-Negative Least Squares for Grant-Free Random Access
Narges Mohammadi Sarband, Ema Becirovic, Mattias Krysander +2
User activity detection in grant-free random access massive machine type communication (mMTC) using pilot-hopping sequences can be formulated as solving a non-negative least square…
Massively Distributed Antenna Systems with Non-Ideal Optical Fiber Front-hauls: A Promising Technology for 6G Wireless Communication Systems
Lisu Yu, Jingxian Wu, Andong Zhou +2
Employing massively distributed antennas brings radio access points (RAPs) closer to users, thus enables aggressive spectrum reuse that can bridge gaps between the scarce spectrum…
Symbiotic Radio: Cognitive Backscattering Communications for Future Wireless Networks
Ying-Chang Liang, Qianqian Zhang, Erik G. Larsson +1
The heterogenous wireless services and exponentially growing traffic call for novel spectrum- and energy-efficient wireless communication technologies. In this paper, a new techniq…
Max-Min Optimal Beamforming for Cell-Free Massive MIMO
Andong Zhou, Jingxian Wu, Erik G. Larsson +1
This letter develops an optimum beamforming method for downlink transmissions in cell-free massive multiple-input multiple-output (MIMO) systems, which employ a massive number of d…
Using Intelligent Reflecting Surfaces for Rank Improvement in MIMO Communications
Özgecan Özdogan, Emil Björnson, Erik G. Larsson
An intelligent reflecting surface (IRS), consisting of reconfigurable metamaterials, can be used to partially control the radio environment and thereby bring new features to wirele…
RadioWeaves for efficient connectivity: analysis andimpact of constraints in actual deployments
Liesbet Van der Perre, Erik G. Larsson, Fredrik Tufvesson +3
We present a new type of wireless access infras-tructure consisting of a fabric of dispersed electronic circuitsand antennas that collectively function as a massive, distributed an…
