    Hello,

    When I changed the following parameter ”LTE_config.network_source” I got this error:

    By using this simulator, you agree to the license terms stated in the license agreement included with this work

    Error using LTE_load_params_dependant (line 487)
    fixed network source not supported

    Error in LTE_sim_main (line 30)
    LTE_config = LTE_load_params_dependant (LTE_config);

    Error in LTE_sim_main_launcher_demo_femtocells (Line 60)
    output_results_file = LTE_sim_main(LTE_config);

    Hi Oularouf,

    for me the simulation finishes without problem, using the same antenna. Did you change anything else regarding the original parameter setting?

    To your second question: First it seems that you chose a network source that is not supported. If you want to use a predefined network, you have to set LTE_config.network_source = ‘generated’ and LTE_config.network_geometry = ‘predefined’. And secondly: Your original problem doesn’t seem to be related to the network source/geometry.

    Possibly the best idea might be to reset to a fresh version of the simulator and see if the demo simulation with femtocells finishes without errors.

    Best regards,
    Martin

    Dear Martin

    I followed your instruction and I reset the version and tried the LTE_sim_main_launcher_demo_femtocells, as result I had the following errors (at the end of the text below)

    thanks

    Dear Oularouf,

    Your error comes from the fact that the WINNER model is already outdated. The newest Matlab versions don’t support anymore many of the old functions that the WINNER uses. For that you need a Matlab vesrion older that 2014b.

    Best,
    Fjolla
