Hi Alexander,

I'll try to give you some answers.

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.

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.

happy hacking/researching
Johannes
