i am very new to this tool….
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…

Hi Harini,

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

Best,
Martin

Hi
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?

based on your reply…i have changed to fastFadingWrapper.m channel model…but i am getting the following error…pls help me rectify this…

SWITCH expression must be a scalar or character vector constant.

Dear Harini,
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,
Fjolla

No sir….nothing is working out….i have changed channel models also but unable to remove the error..

[Harini]

Dear 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…

[Fjolla Ademaj]

Dear 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,
Fjolla

[Martin Müller]

Hi Harini,

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,
Martin
