[Greg Kazz]

All,

The attached pdf file contains the CMLP study report for your review and 
comment with respect to usage of CCSDS recommendations.

Please let me know if you have any comments before the due date of July 5.

>Dear SLS members,
>This CMLP report would deserve a brainstorming meeting to review the large
>amount of information it contains. I have noted with pleasure that it makes
>extensive reference to CCSDS in its pre-selections of modulations and codes.
>However I have noted some inconsistencies, e.g. some mods & codes said to be
>CCSDS-standard when they are not. Also I believe we should cross-check the
>frequency bands usage (though strictly speaking this is not a CCSDS
>business). Finally, the document confirms the apparent intention to go
>multiple access for some links (for TDRSS compatibility only or also for
>other reasons?). I have noted that for MA not only the TDRSS standard CDMA
>(direct sequence spread spectrum) mode is considered but also all other
>existing MA modes. Reason for that is unclear to me: new TDRSS-independent
>applications or new modes for TDRSS?
>I believe we should accomodate a 1/2-day time-slot at Fall CCSDS to this
>brainstorming.
>
>In the meantime, I propose that you review the document and send the comments
>to me, copy to all. I will generate a synthesis dossier of our comments.
>Please provide your inputs by July 5.
>Feel free to circulate the document among your WGs members.

>Thanks in advance
