## Hi Johannes, Could you share the LTE record data that you used in gr-lte?

Thanks

Hi Tiankun,

the recorded files are simply to large to share. (\> 1GB)  
Also, you probably want to record your own data.

This gets us to the second option. Generated test data. Using the  
integrated Python files to generate test data is unfortunately  
incomplete. Used channels can be generated and mapped to its REs but  
OFDM part etc. is missing. If you can extend it I’ll be more than glad  
if I can merge it.  
A third option I learned about recently is to use matlab with lte  
toolbox. I doubt it makes any sense to share such generated files.  
Also I’m not entirely sure about legal implications here.

Cheers  
Johannes

I could provide storage space for such a file, but only at an upstream  
of 10  
Mbps.

Ralph/Johannes,
