QRIS: A QuaDRiGa-Based Simulation Platform for Reconfigurable Intelligent Surfaces

Reconfigurable Intelligent Surfaces (RISs) are a promising way to improve the performance of wireless networks. However, despite the high interest in the research community, no flexible enough simulation platform allows for studying the performance of wireless communication systems with RIS in complex scenarios. To address this issue, the paper presents an open-source channel simulation platform to study RIS in wireless communication systems. The developed open-source platform extends the QuaDRiGa channel model, which is widely used for the performance evaluation of 5G and Wi-Fi networks with multiple antennas. The paper shows how to use the platform — called QRIS — to evaluate RIS in various frequency conditions, such as indoor/outdoor scenarios and multiple-RIS deployments.
