Abstract
Research and development of mobile communications systems require a detailed analysis and evaluation of novel technologies to further enhance spectral efficiency, connectivity and reliability. Due to the exponentially increasing demand of mobile broadband data rates and challenging requirements for latency and reliability, mobile communications specifications become increasingly complex. For this reason, analytic analysis as well as measurement-based investigations of link-level methods soon encounter feasibility limitations. Therefore, computer-aided numeric simulation is an important tool for investigation of wireless communications standards and is indispensable for analysis and development of future technologies. In this contribution, we introduce the Vienna 5G Link Level Simulator, a Matlab-based link-level simulation tool that facilitates research and development in mobile communications. Our simulator enables standard compliant setups according to 4G LTE, 5G NR and even beyond, making it a very flexible simulation tool. Offered under an academic use license free of charge to fellow researchers, it considerably enhances reproducibility in wireless communications research.
Highlights
Link-level measurements, analysis and simulation are fundamental tools in the development of novel wireless communication systems, each offering its own unique benefits
We introduce the newest member of our suite of Vienna Cellular Communications Simulators (VCCS), the Vienna 5G link level (LL) Simulator, to the community
The Vienna 5G LL Simulator acts in close orchestration with its sibling the Vienna 5G system level (SL) Simulator: the LL simulator is employed to determine the physical layer (PHY) abstraction models utilized on SL to facilitate computationally efficient simulation of large-scale mobile networks
Summary
Link-level measurements, analysis and simulation are fundamental tools in the development of novel wireless communication systems, each offering its own unique benefits. The Vienna 5G LL Simulator acts in close orchestration with its sibling the Vienna 5G system level (SL) Simulator: the LL simulator is employed to determine the PHY abstraction models utilized on SL to facilitate computationally efficient simulation of large-scale mobile networks The goal of this contribution is to introduce the Vienna 5G LL Simulator to the research community and offer this versatile and flexible simulation tool under an academic use license free of charge to enhance reproducibility in research. The existence of various simulation tools for the PHY of LTE, such as [20, 21] or the Vienna LTE-A LL Simulator [3, 6, 7], developed by our research group, supports this claim These tools, are mainly based on 3GPP Release 8 to Release 10 and do not offer features and functionality specified and expected for 5G.
