Leveraging Slowly Time-Varying AP-AP Channels for Interference Mitigation in Dynamic TDD
Martin Andersson, Tung T. Vu, Pål Frenger +2
We address the challenge of cross-link interference in dynamic time-division duplexing (TDD) systems. Specifically, we focus on mitigating the interference caused by access points…
A Flexible Framework for Grant-Free Random Access in Cell-Free Massive MIMO Systems
Sai Subramanyam Thoota, Erik G. Larsson
We propose a novel generalized framework for grant-free random-access (GFRA) in cell-free massive multiple input multiple-output systems where multiple geographically separated acc…
Reducing Dynamic Range in Bistatic Backscatter Communication via Beamforming Design
Ahmet Kaplan, Diana P. M. Osorio, Erik G. Larsson
Considering the exponential growth of Internet-of-Things devices and the goals toward sustainable networks, the complexity should be focused on the infrastructure side. For a massi…
Propagation Distance Estimation for Radio over Fiber with Cascaded Structure
Dexin Kong, Diana Pamela Moya Osorio, Erik G. Larsson
Recent developments in polymer microwave fiber (PMF) have opened great opportunities for robust, low-cost, and high-speed sub-terahertz (THz) communications. Noticing this great po…
User-to-User Interference Mitigation in Dynamic TDD MIMO Systems with Multi-Antenna Users
Martin Andersson, Tung T. Vu, Pål Frenger +1
We propose a novel method for user-to-user interference (UUI) mitigation in dynamic time-division duplex multiple-input multiple-output communication systems with multi-antenna use…
Access Point Selection for Bistatic Backscatter Communication in Cell-Free MIMO
Ahmet Kaplan, Diana P. M. Osorio, Erik G. Larsson
Backscatter communication (BC) has emerged as a key technology to satisfy the increasing need for low-cost and green Internet-of-Things (IoT) connectivity, especially in large-scal…
Distributed Signal Processing for Extremely Large-Scale Antenna Array Systems: State-of-the-Art and Future Directions
Yanqing Xu, Erik G. Larsson, Eduard A. Jorswieck +3
Extremely large-scale antenna arrays (ELAA) play a critical role in enabling the functionalities of next generation wireless communication systems. However, as the number of antenn…
Joint Optimization of Switching Point and Power Control in Dynamic TDD Cell-Free Massive MIMO
Martin Andersson, Tung T. Vu, Pål Frenger +1
We consider a cell-free massive multiple-input multiple-output (CFmMIMO) network operating in dynamic time division duplex (DTDD). The switching point between the uplink (UL) and d…
Robust Covariance-Based Activity Detection for Massive Access
Jianan Bai, Erik G. Larsson
The wireless channel is undergoing continuous changes, and the block-fading assumption, despite its popularity in theoretical contexts, never holds true in practical scenarios. Thi…
Decentralized Algorithms for Out-of-System Interference Suppression in Distributed MIMO
Zakir Hussain Shaik, Erik G. Larsson
Out-of-system (OoS) interference is a potential limitation for distributed networks that operate in unlicensed spectrum or in a spectrum sharing scenario. The OoS interference diff…
Stability Analysis of Interacting Wireless Repeaters
Erik G. Larsson, Jianan Bai
We consider a wireless network with multiple single-antenna repeaters that amplify and instantaneously re-transmit the signals they receive to improve the channel rank and system c…
Reciprocity Calibration of Dual-Antenna Repeaters
Erik G. Larsson, Joao Vieira, Pål Frenger
We present a reciprocity calibration method for dual-antenna repeaters in wireless networks. The method uses bi-directional measurements between two network nodes, A and B, where f…
Strong Convergence of a Random Actions Model in Opinion Dynamics
Olle Abrahamsson, Danyo Danev, Erik G. Larsson
We study an opinion dynamics model in which each agent takes a random Bernoulli distributed action whose probability is updated at each discrete time step, and we prove that this m…
Massive Synchrony in Distributed Antenna Systems
Erik G. Larsson
Distributed antennas must be phase-calibrated (phase-synchronized) for certain operations, such as reciprocity-based joint coherent downlink beamforming, to work. We use rigorous s…
