Add Python script to plot logged buffers. Modified write_file_matlab() to add .bin extension if binary format is selected.
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:
- Plots frequency domain channel estimates, constellation diagram and LLRs from data read in binary format. The data is generated from
nr_dlsim -w - Plots BER (other also possible) from CSV data generated by
nr_dlsim -Z.
The plots are saved in three formats: .png, .pdf and .svg.
