calculated SNR traces?

Although this is a bit off topic here: Is there anybody around who can 
help me with generated SNR traces for Rayleigh channels?

I would particularly appreciate getting in touch with an EE or CE guy, 
because this is not mainly a CS topic.

Thanks

Detlef

Re: calculated SNR traces?

Greetings Detlef,

What sort of help would you like?

There is a Matlab/octave script to generate Rayleigh fading at:
<http://www.mathworks.com/matlabcentral/fileexchange/1608-rayleigh-fading-simulation>

Is that what you're after?

Cheers,
Lachlan

Basically yes.

Because I don't have a Matlab-license, it is nessecary for the script to 
run in octave. (Although it is often no big deal to adapt the script, I 
don't want to do this myself, because I cannot check the plausibility of 
the results. I would be more comfortable to do this in cooperation with 
some EE or CE guy.)

Re: calculated SNR traces?

Is there no one to get in touch with?

I'm not quite sure, how anyone can deal with TCP/IP in wireless 
networks, when there is no one to know anything reliable about wireless 
channels.

Perhaps, one could give me a hint, where I could find people to talk to 
about these things?

Thanks.

Detlef

Some time ago I validated radio propagation models in ns3.

Under

http://jauu.net/data/pdf/propagation-models.pdf

you will find a presentation. With all the math: wave length, system loss,
antenna gain, bolzmann constant, receiver noise, Nakagami model including
information how to interpret the results (e.g from SNR to Symbol Error Rate
(for QPSK, QAM, ...)

The presentation is completely generated: including source code for Nakagami
and so on. All you need is a C compiler and the GNU scientific library.

git clone http://git.jauu.net/wireless-propagation.git

If you understand the source - all your questions are answered. ;-)

I explicitly asked to get in touch with someone.

I case someone is explicitly not willing to do so, I don't see a value 
in his contribution to this thread. This  is a scientific discussion 
group. When people reject the scientific discussion, I raise the 
question whether this group is an appropriate venue for these people.
