The QUAsi Determinstic RadIo channel GenerAtor (QuaDRiGa) channel model
is a Matlab based tool for generating radio channel impulse responses
in multi-node networks of radio devices :footcite:`2014:jaeckel,2014:burkhardt`.
It is integrated into Hermes as a channel model plugin, with the generation of new channel realizations
triggering an execution of Quadriga's Matlab scripts via either the Matlab Python API or Octave.
Please refer to the :doc:`/installation` hints for the required setup.
