Functional Description
Pre-Slicer Setting:
During the GAP time there is high sensitivity to jammer, especially if the jammer is close
to the bit rate or 1/2 bit rate.
The Pre-Slicer helps to suppress jammer during the GAP time. Therefore, in TSI GAP
mode, and in TSI GAP mode only should the Pre-Slicer be enabled using the default
settings.
