Hi, Experts;
I have a question on tap parameter definition in .ami file. The current
standard states that:
If in addition the individual tap weights are each given a name
which is their tap number (i.e., "-1" is the name of the
first precursor tap, "0" is the name of the main tap, "1" is
the name of the first postcursor tap, etc.) and the tap
weights are declared to be of type Tap, then the EDA platform
can assume that the individual parameters are tap weights in
a tapped delay line
This way we have to assume that Tx only has FFE and Rx only has DFE.
What if Rx has both FFE and DFE? How can we tell which group of taps is
FFE and which is for DFE?
Thanks in advance.
