<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">Dear Jean-Pierre,</span>
<br>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">a few high level comments from me. I have some more detailed comments on paper, and among those a lot of editorial ones, but I don't have the time to put them down for the time being. I would suggest
that a further review on your side</span> <br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">try to work on the editorial aspects as well.</span>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">My main concerns for the moment are the following:</span>
<br>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">- the document seems to be heavily built around the use of VCM/ACM. While I agree that this will be eventually needed, I was under the impression, after the London meeting, that it was agreed to
leave this out until the VCM Magenta Book is ready</span> <br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif""> Now I see that VCM/ACM have been changed with "DVB-S2" VCM/ACM, but that doesn't seem to change things.</span>
<br>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">- One of the most important things I go to Green Books for are the performance of the standard they support. I see an effort in this sense, under ideal conditions (AWGN), which I appreciate, but
unfortunately the reader in this case may need to go to </span><br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif""> a difference source (ETSI)
</span><br>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">- On the use (or not) of pilots, I understand you plan to add some additional figures, it would be really useful to indicate which (reference) receiver has been considered for the simulations</span>
<br>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">- Similarly, for the results provided on the non-linear channel, it would be useful to know the reference receiver used, as well as the assumptions taken for the transmitter (pre-distortion?)</span>
<br>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">- Still on the non-linear channel results: what you provided is relative to a particular mode of operating a link with VCM (or ACM). While this can be an useful indication, I would find more useful,
at this stage, to have indication on the operating points</span> <br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif""> for each ModCod, not necessarily assuming VCM/ACM. Again, I believe this would give good initial estimates to potential users.</span>
<br>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">I believe we will need to discuss further at the Spring meeting.</span>
<br>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">Have a nice weekend</span>

Dear Massimo</span> <br>
<span style="font-size:10.0pt;font-family:"Calibri","sans-serif""><br>
Following CNES action AI_14_14 at CCSDS fall meetings, here is an update of the DVB-S2 green-book including modifications according to the WG comments (modifications visible in the second pdf document)
</span><br>
<span style="font-size:10.0pt;font-family:"Calibri","sans-serif""><br>
We will provide the 2 missing figures/simulations for the spring meetings</span> <br>
<span style="font-size:10.0pt;font-family:"Calibri","sans-serif""><br>
If you can transmit these documents to the WG, it seems possible to have the WG comments at mid-February, and then it could be possible to propose another updated document for CCSDS spring meetings</span>
<br>
<span style="font-size:10.0pt;font-family:"Calibri","sans-serif""><br>
I wish you a nice christmas</span> <br>
<span style="font-size:10.0pt;font-family:"Calibri","sans-serif""><br>
Best regards</span> <br>
