On the Impact of Random Actions on Opinion Dynamics
Olle Abrahamsson, Danyo Danev, Erik G. Larsson
We study opinion dynamics in a social network with stubborn agents who influence their neighbors but who themselves always stick to their initial opinion. We consider first the wel…
MMSE-Optimal Sequential Processing for Cell-Free Massive MIMO With Radio Stripes
Zakir Hussain Shaik, Emil Björnson, Erik G. Larsson
Cell-free massive multiple-input-multiple-output (mMIMO) is an emerging technology for beyond 5G with its promising features such as higher spectral efficiency and superior spatial…
Max-Min Power Control in Downlink Massive MIMO with Distributed Antenna Arrays
Noman Akbar, Emil Bjornson, Nan Yang +1
In this paper, we investigate optimal downlink power allocation in massive multiple-input multiple-output (MIMO) networks with distributed antenna arrays (DAAs) under correlated an…
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…
