[SLS-CC] ECSS-E-ST-50-01C Annex A vs. CCSDS 131.0-B Annex F

[Gian.Paolo.Calzolari at esa.int]

Dear All,
        in a meeting about possible ECSS Adoption Notes for CCSDS docs to 
replace some ECSSS standards, Marjorie de Lande Long has pointed out the 
following difference between the two standards: 
R-S Berlecamp Annex, Table Equivalence of Representations: ECSS underlines 
entries that correspond to values with exactly one non-zero element and 
match a row in the matrix.

I suggest that the C&S WG consider in the next meeting whether modifying 
Annex F of CCSDS 131.0-B to use the same approach of the ECSS book.
Most likely, the change would be limited to adding a note (like note b 
that you find in page 48 of the ECSS Standard) and underlines the values 
to which this is applicable.

To support the discussion I have uploaded in CWE (Directory: The CCSDS 
Collaborative Work Environment (CWE) > Space Link Services Area (SLS) > 
Documents > SLS-CandS > Meeting Materials > 2015 > 2015_11 Darmstadt > 
CCSDS131.0-B.AnnexF  ; http://tiny.cc/vd1a0x ) the following documents:
- The referenced standard: ECSS-E-ST-50-01C(31July2008).pdf
- Some considerations of GF 256 from POLITO (thanks to Prof. Garello): 
POLITO_on_GF256
- A paper referenced in those considerations: 
Truong,Deutsch,Reed,Hsu,Wang,Yeh-70H.pdf

Of course some material may even be included in the Coding Green Book when 
an update will be done.

Regards

Gian Paolo
