QuaDRiGa, short for QUAsi Deterministic RadIo channel GenerAtor, is 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 multi-link tracking of users (receiver) movements in changing environments.

The new version (v2.0) 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 supported (standardized) channel models are:

DOCUMENTATION

The technical documentation gives a detailed overview of the QuaDRiGa channel model, its implementation details and tutorials providing examples for usage. The model has been evolved from the WINNER channel model described in WINNER II deliverable D1.1.2 v.1.2. This document covers only the model itself. Measurement campaigns covering the extraction of suitable parameters can be found in the WINNER documentation. Furthermore, the MIMOSA project covers the model development and parameter extraction for land-mobile satellite channels.

Release notifications

The channel model is parametrized for various applications and scenarios, e.g. urban macrocellular (UMa) or urban microcellular (UMi). The model parameters for these scenarios are either based on measurement campaigns or on standardized models. While a multitude of common configuration files comes with the QuaDRiGa implementation, additional parameterizations based on single measurement campaigns are available here.
