sionna.phy.fec.utils.plot_trajectory(plot, mi_v: numpy.ndarray, mi_c: numpy.ndarray, ebno: float | None = None) None[source]#

Plots the trajectory of an EXIT-chart.

This utility function plots the trajectory of mutual information values in an EXIT-chart, based on variable and check node mutual information values.

Parameters:
  • plot – A matplotlib figure handle where the trajectory will be plotted.

  • mi_v (numpy.ndarray) – Array of floats representing the variable node mutual information values.

  • mi_c (numpy.ndarray) – Array of floats representing the check node mutual information values.

  • ebno (float | None) – The Eb/No value in dB, used for the legend entry.

Note

This function does not return a value; it modifies the provided plot figure in-place.
