 This means that the channel profile changes the effective link robustness even though all other baseline parameters are kept constant. The difference is caused by the different multipath and fading behavior represented by the NTN-TDL profiles.

 Since this plot shows only one representative packet at 30 dB SNR and 320 MHz bandwidth, it should be interpreted qualitatively. It illustrates how the different channel profiles affect the frequency response, while the PER sweep provides the statistical performance comparison.
