Fingerprint-Based Localization and Channel Estimation Integration for Cell-Free Massive MIMO IoT Systems

In this article, we propose a novel localization and channel estimation integration framework for cell-free massive multiple-input-multiple-output (MIMO) Internet of Things (IoT) systems, in which position information supports accurate channel estimation and accurate channel information can, in turn...
