C++ 11 is supported in the next branch:

Hello,
I noticed that the fastnoise_source block is not thread safe, as it
calls rand(), which keeps global state.
This makes it non-reproducable between multiple runs once more than one
such source is used.
I also opened an issue about this on github:
https://github.com/gnuradio/gnuradio/issues/
Orthogonality (as the O in OFDM) guarantees a fixed phase relationship for
every symbol unless a pattern is introduced in an effort to reduce peak to
average power ratio (which I do not believe is happening here). PAPR is
bane of OFDM and much research has gone in to reduce this problem which
requ
Try breaking this up into 3 separate programs and start the receivers
first. It might be that the receivers aren't even getting started before
the transmitter is done.

I can't understand your setup from the description, maybe a GRC file or
source code would help. In any case, it sounds like you may have 3 USRPs
tied together in one flowgraph, which could cause a problem.

Hi Jeff,
Thank you for your quick response. I didn't do anything with the clock sync
since I don't have gpsdo embedded on the N210 or any sync devices. I just
used the normal setting for usrp_source and usrp_sink. I set up the antenna
for tx gain to 35 and rx_gain to 15. I assume the clock sync i
How are the clocks in the N210s synced? What rates are you using? What
symptoms are you seeing that tell you the sinks are not receiving packets?

Hallo guys,
I have a configuration using gnuradio-companion as follows;

The devices I am using are USRP N210s and it is with
