Re: [Discuss-gnuradio] LTE and USRP

[Coll Perales, Baldomero]

Thanks Paul,

LibLTE looks like very promising. I'll follow the advances. By the way, do you 
know if it will be compatible with USRP2 or only with new ones (N Series - 
UHD-based)?

Thanks,
Baldo

Hi Baldo,

There is also LibLTE - https://github.com/libLTE/libLTE It's a modular LTE 
library with minimal external dependencies. It's compatible with UHD devices 
and is LGPLv3.
It's under development but currently provides eNodeB and UE implementations for 
most of the downlink. Among the example programs are downlink PSS and MIB 
scanners as well as an initial UE implementation which receives and demodulates 
the downlink broadcast channel (PBCH).
The UE example has been tested with both test and live commercial eNodeBs.
As it's a modular library, it doesn't depend on a specific framework like 
gnuradio but can be used easily in most SDR frameworks. We're currently porting 
the UE example to gnuradio and hope to make it available soon.

Regards,
Paul
