What does LA, SC, and QC mean in SD-FEC of RFSoC?

What does LA, SC, and QC mean in SD-FEC?

 

I get quasi-cyclic for QC (please confirm)

 

I guess SC might be staircase or spatially coupled...

 

LA I am not so sure about.

 

Also, you should probably define in PG256.

Hi @maps-mpls ,

As noted, there is no expansion defined for SC, LA and QC terms.

SC_Table contains the scaling terms, hence termed as SC_TABLE.

LA contains the information for each layer of the code, hence LA_Table.

QC_table contains the information of circulants of the Quasi cyclic LDPC code's base matrix.
