Plotting tools

ul_bler_vs_snr_graph.py

This generates UL BLER vs SNR plots using nr_ulsim. It uses cache so subsequent runs are faster. Assumes your nr_ulsim is in ../../cmake_targets/ran_build/build. Run with -h flag to see options

Example graph:

Cache usage and modifting nr_ulsim command

Modify the script call to nr_ulsim if you want a different channel model or other flags in the nr_ulsim command. Remember to clear the cache (remove cache.pkl from this folder) so that the results from a different run are not taken from the cache.

Same goes for any software modifications of nr_ulsim - the cache is not aware of the software version used to generate the data - remember to clear your cache manually if you are comparing different nr_ulsim versions.

The script also allows to skip usage of the cache with --rerun option.

dl_graph.py

This generates plots from data saved from nr_dlsim. It takes data in two formats:

  1. Plots frequency domain channel estimates, constellation diagram and LLRs from data read in binary format. The data is generated from nr_dlsim -w
  2. Plots BER (other also possible) from CSV data generated by nr_dlsim -Z.

The plots are saved in three formats: .png, .pdf and .svg.

Example graphs:
