Hi Ali,

I assume you pulled the latest gr-lte Version this week and you're
using the _siso.grc flowgraph.

Does your file source repeat the frames you generated? Maybe the
flowgraph gets stuck before the PBCH path receives any samples.

While PBCH, BCH, MIB decoding is rather robust, synchronization etc.
are sometimes a little fuzzy. I'd assume some part of the system is
getting this wrong here.

Maybe a screenshot of your flowgraph with all the parameters helps to
clarify your problem.

Also try to attach a GUI sink after synchronization and channel
estimation. It might help to further determine the source of the problem
.

Cheers
Johannes
