ok, I think I know where the confusion comes from.
In LTE_sim_main_launcher_demo_basic.m, there is the line
% LTE_config.eNodeB_tx_power = 46; % 46 dBm
The problem here is, that the TX power is specified in Watt, and that it says dBm here is a mistake. If you check the corresponding config file +simulation_config/hex_grid_tilted.m, you find in line 104
LTE_config.eNodeB_tx_power = 40; % eNodeB’s transmit power, in Watts.
The SINR calculation in the UE file is thus consistent, all values are linear.
We will updated the launcher file and get rid of the ‘dBm’ to avoid further confusion. Not sure how it got there, sorry about that…
If you have further questions, please let me know!
