Hello!
I tried to run a simulation with carrier aggregation (located in folder repdroducibility).
But the folder data_files is missing. So there is an error when trying to run a CA simulation.How may I fix this issue?
Thank you in advance!

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;
LTE_config.fft_points = 10240;
switch LTE_config.cyclic_prefix
case ‘normal’
LTE_config.CP_length_samples = 720;
case ‘extended’
LTE_config.CP_length_samples = 2560;
end
otherwise
error(‘Bandwidth not supported’);

There was a bug in the carrier aggregation version. The folder data_files was missing. Please copy the folder data_files from the main directory of the simulator into reproducibility/Carriera Aggregation/Vienna-LTE-A-SLS-v1-9-Q1-2016-Carrier-Aggregation.
Best regards,
Fjolla -
