filtering of OQPSK - proposed editorial changes to CCSDS 413.0-G-3</span>

<br><span style=" font-size:10pt;font-family:sans-serif">Dear All,</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">I was recently
approached by European industry on the correctness of figures 3-25 and
3-26 in the green book on bandwidth efficient modulation. The industry
was confused about the use of symbol rate and suggested it should be the
channel symbol rate instead. After an exchange with the NASA authors of
the relevant section 3.2.2.3.2.1 "Baseband Filtered OQPSK with a Square
Root Raised Cosine Filter", it was determined that there was nothing
wrong with the two figures. Simulations were done again and returned the
same plots.</span>
<br><span style=" font-size:10pt;font-family:sans-serif">However, we agreed
that some additional explanations would help readers in understanding this
section better and avoiding confusion in future.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">The proposed revision
marks in the attachment are the agreed ESA/NASA additions. Note that we
consider them just editorial improvements.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">If I do not receive
any negative comments from you by February 7, I will assume RFM WG concurrence
and submit the attachment to the CCSDS Editor via the SLS Area Director.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Best Regards,
Enrico</span>
<br>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">P.S. Please note
that since I just pasted the whole section (and the previous one) of the
green book into a blank document, you will get a number of missing references
when printing the two pages. Just look at them on the screen or disable
the reference updating function when printing.</span>
