[SLS-CC] 131.20-O draft Orange Book (SCCC-X) WG review -> Deadline 17 December

[Enrico.Vassallo at esa.int]

Dear Andrea,

I noted that the pictures of Bit Mapping into 128/256APSK Constellations 
appear to be vertically squeezed (well known MATLAB problem) so that the 
shape is elliptical and not circular. In light of similar issues we had 
with lower order constellations (had to have them redrawn for the RFM 
recommendations), it would be good if you could fix the problem and 
generate better pictures.

Regards, Enrico

17 December


Dear colleagues,

ESA (Andrea) just provided an updated version of the SCCC-X (131.20-O) 
Orange Book, including the simulation results (annex), as agreed in 
Darmstadt (AI_19_11 in the minutes).
With this message, I would like to start the WG review.
Similarly to the on-going review of the DVB-S2X Orange Book, your comments 
are expected by in 6 weeks, with deadline 17 December.
As for other WG reviews, we don't have a standard format for the comments. 
You can use the standard CCSDS RID format used for Agency Review, if you 
wish so, but you are not
obliged to do so.
Please address the comments to Andrea (andrea.modenini at esa.int) and 
myself, we will take care of collecting them.
If you wish, you can also use the following CWE area to leave your 
comments (in that case I would appreciate if you let me know)
