Abstract
Reducing decision based filter error propagation by feedback from a physical coding sublayer (PCS) to a slicer. One method includes: receiving a frame comprising symbols of at least two different modulation orders that use subsets of a symbol superset; slicing the received symbols according to the highest modulation order by a slicer having slicing functions suitable for the different modulations; identifying frame boundaries and modulation information, which are modulated according to a predetermined modulation order; using the identified modulation information for determining the modulation of a nonempty set of dynamically modulated symbols in the received frame; and providing the slicer with an indication of which slicer function output to use for feeding a decision based filter.
