[Discuss-gnuradio] Bandwidth switching per symbol

[bjoernm]

Hi,

I'm currently using the UCLA ZigBee Phy implementation by Thomas  
Schmid and I need to
change the Bandwidth of the used wireless channel on a per symbol basis.

I managed to change it on a per packet basis, which can be done on the  
python level
(tunnel.py, usrp_transmit_path.py etc.). Well now, I need to do the  
same thing, but on a
per symbol basis, which (up to my knowledge) is not possible from the  
python level...

Does anyone have an idea how I could do that? (Changing the Bitrate of  
the USRP after
each symbol (e.g. after sending 32 modulated bits (actually chips)))

I would be very happy for any help or suggestions!
Thanks a lot!

best regards,
Bjorn
