It seems that the winner channel model is not available anymore. We do not provide assistance regarding this, we only provide an open interface that links to this channel model. Please contact the corresponding authors of the WINNER if you want more details.
In order to use other channel models, you don’t need to change the fast fading wrapper. Just set the parameter:
LTE_config.channel_model.type = ‘TU’; % ‘PedB’ ‘PedA’ ‘extPedB’ ‘TU’ ‘Rayleigh’ ‘winner+’
to the desired channel model. This you can do either in the launcher file or in the config file you are using.
