    Hi
    I recently installed Vienna LTE-A simulator and tried to run a sample simulation.
    I am using Matlab2009b.
    And I got the below errors:

    Can you please let me know why this happens? Thanks in advance.

    HI Preethi,

    which simulator version are you using?

    Best regards,
    Martin.

    I am also having the same error and need help for it I am using LTE system level simulator v1.8.

    I am having this error at the launch and using LTE system level simulator v1.8 and need urgent help.

    Hi,

    I couldn’t reproduce the error with MATLAB R2016. The error may be associated with the isempty() function.
    Before starting a simulation, type: dbstop ‘if error’. Then, check the content of current_site_sectors(s_).macroscopic_pathloss_model.

    Best regards,
    Martin.

    Hi Martin,

    Sorry for the late update. I am using v1.9 with Matlab 7.9. Will try as you have mentioned and update.

    Thanks

    Hi Martin

    I apologize for my late reply. I am using LTE-A v1.9 with Matlab 7.9. I will try as you have mentioned in the previous post and update.

    Thanks
    Preethi
