Fraunhofer Releases New Version of its Radio Channel Model for Future 5G Evaluations

Fraunhofer Heinrich Hertz Institute (HHI) has released the QuaDRiGa 2.0, which is a major update of its well-established open-source radio propagation model. QuaDRiGa, short for QUAsi Deterministic RadIo channel GenerAtor, is mainly used for generating realistic radio channel impulse responses for system-level simulations of mobile radio networks. These simulations are used to determine the performance of new technologies in order to provide an objective indicator for the standardization process in bodies like the third generation partnership program 3GPP.

QuaDRiGa was developed at Fraunhofer HHI to enable the modeling of MIMO radio channels for specific network configurations, such as indoor, satellite or heterogeneous configurations. Besides being a fully-fledged three dimensional geometry-based stochastic channel model, QuaDRiGa contains a collection of features created in SCM(e) and WINNER channel models along with novel modeling approaches which provide features to enable quasi-deterministic multilink tracking of users (receiver) movements in changing environments.

The new version of QuaDRiGa contains a couple of new features and is furthermore calibrated against 3GPP channel models like 3GPP-3D and the latest New Radio channel model. The open-source MATLAB/Octave implementation is freely available here.
