HermesPy: An Open-Source Link-Level Evaluator for 6G

In this paper we present the Heterogeneous Radio Mobile Simulator in Python (HermesPy), an open-source evaluator for studies on the physical layer of 6-th generation (6G) wireless systems. The software framework combines a link-level simulator, featuring a comprehensive set of models and algorithms, with hardware in the loop verification using software-defined radios. Among other features, it supports the evaluation of multi-node joint communications and sensing scenarios, which are likely to be one of the key features in 6G. We benchmark the framework’s feature set against existing simulators and introduce its architectural concept. Finally, extensive simulation results demonstrating core functionalities are presented and discussed.
