I have been trying to discover what is currently available in terms of
source, working out-of-the box, modules implemented in GNU Radio and the
USRP, to use as a teaching aid with students.
I am interested in a few things, waveform generation, protocol stacks
Are there working examples for producing 3G, UMTS, LTE, WiMAX signals
etc.? Are there implementations including MAC layer support?
Are there any implementations of a ‘test vector analyser’?
What is available in terms of complete protocol stacks? I understand
there is openBTS, though I read somewhere it is not yet compatible with
current version of GNU Radio. Is this true? What about openLTE?
Is there a repository for such projects that are updated that I have
come across yet?
I have yet to find any real solid leads in my research for solutions.
are vague references to such projects, or papers and examples circa
that I think are now depreciated in terms of GNUradio 3.7 compatibility.
Any info/pointers would be greatly appreciated.

I’ll try to give you some answers.
- Are there working examples for producing 3G, UMTS, LTE, WiMAX
signals etc.? Are there implementations including MAC layer
gr-lte might be interesting for you, if a PHY layer implementation of
LTE is of interest. At least it is designed to use GR blocks and be
easy to see which processing steps are to be done one after another.
Also it is completely ported to GR 3.7.
Also recently there was an announcement for gr-cdma. This might be
interesting in terms of 3G/UMTS.
- What is available in terms of complete protocol stacks? I
understand there is openBTS, though I read somewhere it is not yet
compatible with the current version of GNU Radio. Is this true?
What about openLTE?
To the best of my knowledge, openBTS and GR have diverged since then.
openLTE is a very interesting LTE implementation which supports GR 3.7
if I interpret the commit messages correctly.
