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…
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…
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…
User-to-User Interference Mitigation in Dynamic TDD MIMO Systems with Multi-Antenna Users
Martin Andersson, Tung T. Vu, PÃ¥l 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…
