unable to run this particular code LTE_sim_main_launcher_demo_femtocells.m …..
Error using channel_gain_wrappers.winnerChannelFactory.prepare_winner_channel_model_path (line 51)

it into the “./Winner Channel Model” folderError in LTE_load_params_dependant (line 622)

when i am running LTE_sim_main_launcher_demo_femtocells.m…-
i am finding below error…and also i am unable to download ….the Winner+ II channel model from http://projects.celtic-initiative.org/winner+/phase_2_model.html….
please help me…

if you are not particularily interested in using the Winner channel model, I suggest you simply use another one, like PedA or TU.
Best,

I am unable to download the Winner+ II channel model from http://projects.celtic-initiative.org/winner+/phase_2_model.html . the requested page does not exist. where can i download the Winner + II channel model?- This reply was modified 3 years, 11 months ago by Avinash.
4. July 2018 at 7:19 #10737HariniParticipantbased on your reply…i have changed to fastFadingWrapper.m channel model…but i am getting the following error…pls help me rectify this…

Dear Avinash,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.
Best regards,
Fjolla13. July 2018 at 12:32 #10845HariniParticipantNo sir….nothing is working out….i have changed channel models also but unable to remove the error..
13. July 2018 at 12:35 #10846HariniParticipantDear Martin sir,
Everytime i run i am getting new type of errors sir…please do modifications in this LTE_sim_main_launcher_demo_femtocells.m….and reload the program sir….so that i can learn…16. July 2018 at 11:33 #10862Fjolla AdemajMemberDear Harini,
There is nothing wrong with our launcher files, probably you changed the code and this is causing several errors for you. I recommend to download the launcher file from the beginning and only change the channel model type as I suggested above.
Best regards,

it looks like your computer is running out of memory. You might want to scale down the size of your simulation to overcome this problem.
Best regards,
