    hello

    Thanks again
    I am interested in comparing schedulers and adding a new one based on other theorems such us ”game theory’ and others

    So i didnt change a lot of parameters i only specified the name of the predefined schedulers, in order to figure out how, where and what files I have to change to add my new scheduler

    Please find below the parametsr

    close all force;
    clc;
    cd ..

    %clear global;
    %clear classes;

    simulation_type = ‘tri_sector_plus_femtocells’;

    % – ‘omnidirectional_eNodeBs’

    LTE_config = LTE_load_params(simulation_type);

    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
