    Dear Fjolla

    Thanks in advance, I have checked the User macroscopic path loss. SO, I have query….IS the obj.downlink_channel.macroscopic_pathloss calculate by using for example TS 36.942 pathloss model and by dual slop path loss model. I am simulating LTE_sim_main_launcher_demo_femtocells

    user_macroscopic_pathloss_lin = obj.downlink_channel.macroscopic_pathloss .* (10.^(obj.wall_loss/10)) ./ (10.^(obj.antenna_gain/10));

    regards

    Hi Fjolla Ademaj,..Thanks in advance

    does the interference power for each RB can be calculated by this equation ?
    Interference power for each RB = Power of RB – macroscopic pathloss…

    I set up the shadow fading as none…LTE_config.shadow_fading_type = ‘none’;

    Regards

    there is a file named by LTE_load_params_dependant.m…you will find it set it up to 20MHz bandwidth, so you should recalculate the RB, CP ..ets for example the Bandwidth (40, 60, 80, 100 )MHz…such as the the code blow

    case 20e6
    LTE_config.N_RB = 100;
    LTE_config.fft_points = 2048;
    switch LTE_config.cyclic_prefix
    case ‘normal’
    LTE_config.CP_length_samples = 144;
    case ‘extended’
    LTE_config.CP_length_samples = 512;
    end
    case 40e6
    LTE_config.N_RB = 200;
    LTE_config.fft_points = 4096;
    switch LTE_config.cyclic_prefix
    case ‘normal’
    LTE_config.CP_length_samples = 288;
    case ‘extended’
    LTE_config.CP_length_samples = 1024;
    end
    case 60e6
    LTE_config.N_RB = 300;
    LTE_config.fft_points = 6144;
    switch LTE_config.cyclic_prefix
    case ‘normal’
    LTE_config.CP_length_samples = 432;
    case ‘extended’
    LTE_config.CP_length_samples = 1536;
    end
    case 80e6
    LTE_config.N_RB = 400;
    LTE_config.fft_points = 8192;
    switch LTE_config.cyclic_prefix
    case ‘normal’
    LTE_config.CP_length_samples = 572;
    case ‘extended’
    LTE_config.CP_length_samples = 2048;
    end
    case 100e6
    LTE_config.N_RB = 500;

    thank you for your reply

    I have another query, could you tell me about the exact equation that used to calculate (UE throughput),please. regards

    Hello Naser

    please I asked about the techniques mitigation that used in this simulator but nobody has answered me. So have an idea about the interference mitigation technique between Macrocell and femtocells; and between neighbouring femtocells …regards

    Hi

    does anyone know where is the setting up of LOS

    thanks again for your reply..

    so I have used TS 36.942 for only macrocells deployment, while for femtocells overlaid with macrocell deployment i have used dual slop path loss model. but I didn’t note increasing in throughput

    thank you for your reply …
    i have another query if you could to help me…. i have used the carrier frequency (5GHz) but the throughput didn’t increase…my question why the throughput didn’t increase with increasing of carrier frequency?
