The DFE tab is used in TES to set up the CFR engines as shown in Figure 57.
Figure 57. CFR Engine Setup Using TES
‘Load File’ can be used to load the correction pulse. This correction pulse is specific to the waveform being used (LTE 20 MHz in
example shown) and is sampled at the peak detection rate. We have set the CFR Peak threshold to 0.47, which would correspond
to a target PAR calculated using the following equation
Using the equation above, the target PAR is around 8.75 dB. On the other hand, if the user wants to derive the CFR peak
threshold value needed for achieving a desired target PAR, they can use the equation
The user would then need to enable the required number of CFR engines as shown in Figure 58.
