Dear Jean-Pierre,

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
try to work on the editorial aspects as well.
My main concerns for the moment are the following:

- 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
  Now I see that VCM/ACM have been changed with "DVB-S2" VCM/ACM, but that doesn't seem to change things.

- 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
  a difference source (ETSI)

- 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

- 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?)

- 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
  for each ModCod, not necessarily assuming VCM/ACM. Again, I believe this would give good initial estimates to potential users.

I believe we will need to discuss further at the Spring meeting.

Have a nice weekend
Massimo

Dear Massimo

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)

We will provide the 2 missing figures/simulations for the spring meetings

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

I wish you a nice christmas

Best regards

Jean-Pierre
