Ignacio and Andrea,
<div class=""><br class="">
</div>
<div class="">Here are a few comments in response to discussion during the SLS Plenary.</div>
<div class=""><br class="">
</div>
<div class="">* A list of all projects is available in the CWE Area here:</div>
<div class=""><a href="https://cwe.ccsds.org/fm/Lists/Projects/AllOpenChartersWithAllProjects.aspx" class="">https://cwe.ccsds.org/fm/Lists/Projects/AllOpenChartersWithAllProjects.aspx</a></div>
<div class="">One can scroll down to 5.02, for example, to see an historical list of all projects completed by the Coding and Synchronization Working Group. Given this, I don’t see a good reason to duplicate the list in our charter.</div>
<div class=""><br class="">
</div>
<div class="">* The Optical Communications Working Group charter is available here:</div>
<div class=""><a href="https://cwe.ccsds.org/fm/Lists/Charters/sls.aspx" class="">https://cwe.ccsds.org/fm/Lists/Charters/sls.aspx</a></div>
<div class="">It does include coding for optical links, and in fact, that working group has been standardizing codes for optical links. Hence, I think it makes sense to delete it from the Coding and Synchronization charter.</div>
<div class=""><br class="">
</div>
<div class="">* Andrea’s slides mention that for the 131.2 Blue Book (Flexible Advanced Coding and Modulation, i.e. SCCC), a C&S WG resolution for publication for publication was issued in Fall of 2021. I found an email message dated 11 February, 2022, but
I don’t know that anything has happened since then. I think the next step would be for Ignacio to issue an SLS resolution, so if you could both look back at that and confirm the status, I’d appreciate it.</div>
<div class=""><br class="">
</div>
<div class="">* For the five-year review, the only C&S document that comes to mind is 230.2-G-1, “Next Generation Uplink”, published in 2014. That book provided a roadmap for updating our ground-to-space communications link standards, and we have largely
completed that over the past eight years. We added short-blocklength LDPC codes to the TC Blue Book (231.0-B) in 2017 (updated again in 2021), explained those codes in the TC Green Book (230.1-G-3) in 2021, and permitted the use of the AOS protocol on forward
links in the TM Coding Blue Book (131.0-B-4) and DVB-S2 Blue Book (131.3-B-2) in 2022, and have a resolution pending to do the same with the SCCC Blue Book (131.2-B). Hence, I think we can now retire that Next Generation Uplink Green Book.</div>
