I hope he didn't hit you too hard to "compel" you :-)

The physical layer of CDMA is in my competence, but what you are asking
for is more like network planning modeling, which isn't really what I
do. What type of raw data do you have? Do you already have capacity
against number of users and just want to extrapolate it? Or do you have
something like single user Eb/No results and want to try and convert
that into a multi-user capacity (something much harder)?
The problem with CDMA capacity calculations is that they are very
sensitive to the transmit power control of each of the users, as each
user sees the others as a source of noise and will try to increase their
power to overcome it, which of course doesn't help anyone. So if you are
trying to model such effects you need to make assumptions on the power
control, the distribution of the users, propagation models, etc, etc...
I'm sure octave is capable of modeling this sort of thing, but it'll be
a big effort.
In short I think for anyone to really help you, you might need to be
clearer in what you are asking for.
