[SLS-CC] C&S Pasadena meeting, draft minutes

Wed Apr 1 07:28:11 UTC 2015

Dear Jean-Luc and all,

thank you for reading carefully the minutes.
As far as the DVB-S2 GB is concerned, as long as it is a project under 
SLS/C&S, I believe it's up to me as Chairman to set the tone for the 
discussion, independently from how things are done in other areas or other 
GBs.
You may well disagree with my approach, obviously, and you can raise this 
to whatever level you feel appropriate. I'm copying Gian Paolo so that, as 
Area Director, is informed on the situation.

Coming to the actual comments received, you may have noticed how I pointed 
to a CNES past paper that at least partially addressed these issues. 
Instead of fighting the comment, wouldn't it be more constructive on your 
side
to copy the material already available into the Green Book, possibly 
building on it as appropriate? 
To the best of my understanding, the comments on the GB were meant to 
improve it.
Concerning the reply you are asking me to add, I'm afraid I have no memory 
at all of it from the discussion, and I usually type my notes real-time.
In any case, I would consider it rather damaging to the DVB-S2 GB effort. 
Having the comment on Doppler being raised, the GB discussion would need 
to stop until RFM has dealt with the issue. Is this really what you want?

Best regards,
Massimo

Massimo,

Hope you had a nice trip back.
Thanks for the report. 
We take note of the reporting you made in section 2.7 of the DVB-S2 GB 
update.

We note Wai Fong?s remark concerning the one-agency contribution for this 
GB. We would like to remind that this is common practice, as agencies are 
all too happy that one agency volunteers to do the GB drafting job); It 
was the case recently for the LDPC add-on in the TM Channel C&S GB. It was 
also the case not only of the 415-0G1 CDMA via DRS Green Book but also of 
the Blue Book itself 415-1B1. I wish Wai Fong showed as nitty-gritty with 
the current LDPC Slicing project of C&S which deals with NORMATIVE 
material and still is a single-agency project!

Outside SLS, we could also mention the current CFDP GB project in SIS  or 
the Navigation GB project in MOIMS, which are both single-agency projects.

Concerning Doppler/Doppler-rate questions, we would appreciate if you 
could report on CNES?s reply: ?CNES mentioned that Doppler, if it were to 
be addressed, should be discussed in the frame of the RFM books; it has to 
be noted that the RFM WG never deemed it necessary ? so far ? to address 
Doppler in GBs, such as the GB on BW-Eff Modulations?.

best regards
Jean-Luc
