review - deadline for comments: 16 June 2018

Dear Massimo,

Just a couple of comments on the GB
·         p.vii, the spectral efficiency is expressend in bps/Hz.
p.2-3 and 2-4 the spectral efficiency is expressed in bit/symbol. 
What is the roll-off factor used to compute the spectral efficiency in 
bps/Hz? A coherency for the spectral efficiency unit would be better.
[MB] We'll try to align the use as much as possible, even if, in different 
sections, we refer to different definitions: in 2-3 and 2-4, we talk 
explicitly of bits/symbol, while
          bps/Hz is appropriate when discussing the BW (for which, 0.2 and 
0.35 roll-off were assumed)

·         Chapter 4.3.3 deals with the occupied bandwidth.
A BW is defined for the optimal IBO after filtering with and without 
predistorison. The computation of the corresponding spectral efficiencies 
with respect to the ones given in Table 2-1 would be useful for 
performance estimation (for instance in Tables 6-1 and 6-2).

[MB] We'll see what we can do without distorting too much (putting too 
much information into) the table

Thank you Enrico, 

we'll deal with the comments shortly (we are waiting for the deadline to 
avoid duplications). 
I confirm we'll remove all the normative material already in the Blue Book 
 (your point 4), but possible also the 3)) 

1) ok 
2) ok 
3) see above, I'd rather remove normative material 
4) ok 
5) ok 
6) ok for the proposed change. We'll add more detail about the filter 
(bandpass, stopband...), which is the one that was agreed in the past for 
simulations 
7) it should be feasible 
8) they seem ok in the pdf and word file. We used equation editor. We'll 
hand over the original figures to Tom 
9) with RF filtering. We'll add the information 

Best regards, 
Massimo

Dear Massimo, 

please find below some comments of mine. 

Regards, Enrico 

--------------------------------------------------------------------------- 

1) Title of sections 3 and 4 

I would add "(ideal synchronization)" at the end to distinguish from 
section 6. 

2) Section 1,1, Jon's comment on Earth Observation missions 

I think you should use the ITU terminology: Earth Exploration-Satellite 
Service missions. 

3) Figure 2-6 

You should use the figures from ref [11] instead that look better and 
avoid the issues raised by Wai already with the previous version of this 
document. 

4) Table 2-2 

I think that this normative text is included in [11]. Please confirm. 

5) Figures 3-1 and 3-2 

Add "uncoded" to the captions. 

6) Section 4.1 

The last para starting with "For all simulations .." should appear before 
the previous sentence making reference to figure 4-3 since these data are 
necessary to interpret the figure. Is there anything else we can say here 
about the elliptic filter? I mean, is 5th order enough to get the plot of 
figure 4-3? 

7) Figures 4-19 and 4-20 

Reduce the Y-axis scale to 1.5 from 2.6 so that differences can be 
appreciated. 

8) Equations and figures in 5.2, 5.5 and 5.6 

Some of them appear of low quality on my printouts. Could be my printer. 
Be prepared to get nice originals requests by Tom. 

9) Tables 6-1 and 6-2 

Is the bandwidth with or w/o RF filter? Please add this info.

Massimo,

Attached are my comments on the SCCC Green Book.  Not having the Word 
version, I found it easiest to mark it by hand.  Most of the comments 
relate to English usage, which I hope you will consider, but there are 
many technical comments as well.
