QuaDRiGa

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 digital-radio 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.

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:

• Compatibility with 3GPP TR 36.873 v12.5.0
• Compatibility with 3GPP TR 38.901 v16.1.0
• Compatibility with the mmMAGIC channel model (mmMAGIC D2.2)

QuaDRiGa-NG (v3.x)

QuaDRiGa-NG is an experimental fork of QuaDRiGa (https://github.com/stjaeckel/QuaDRiGa-NG) that implements new features and extensions. The main difference is that some time-critical internal functions such as antenna pattern interpolations, etc., have been implemented in C++ for improved performance.

This functionality is now back-ported into the base-version of QuaDriGa (NG-Branch). It required Quadriga-Lib to work. A copy is placed in the external folder. To compile it on ubuntu, you need to install the following system packages:

sudo apt install bzip2 gcc git make cmake g++ libhdf5-dev python3-dev python3-pytest python3-numpy octave-dev

Then you can simply call make on the command line.

On Windows, you need Visual Studio to compile the code:

• Install Build Tools for Visual Studio 2022 from https://visualstudio.microsoft.com
• Install Matlab from (https://www.mathworks.com) - you need to obtain a licence
• From MATLAB Shell run "mex -setup -v" and select compiler MSVC Compiler
• If error: https://yingzhouli.com/posts/2020-06/mex-msvc.html
• Open "x64 Native Tools Command Prompt" from start menu
• Run nmake to compile quadriga-lib and the MEX Matlab interface

Both, the quadriga_src and the quadriga_lib folder must be added to the MATLAB / Octave path.
