A Joint Channel Modeling, Parameter Estimation and Geometry‐Based Indoor Localization for 5G Systems
Transactions on Emerging Telecommunications Technologies, Volume 37, Issue 6, June 2026.We propose an end‐to‐end method to accurately localize mobile stations in indoor scenarios, such as those found in Industry 4.0. To this end, we jointly perform wireless channel modeling considering mmWave and MIMO technologies, parameter estimation in 3D, and simple and fine‐grained geometry‐based localization.
