I have a setup of one receiver and two transmitters. I am implementing a
TDMA structure (using USRPs and GNURADIO) where only one packet is sent in
each slot. When both transmitters try to transmit in the same slot,
collision occurs. I would like to know
1. How can the receiver detect whether a

Hi Sumedha,
1. You could perhaps look at the average power received over that time
slot. If there is a collision, the receive power would ostensibly be higher.
2. Traditionally, a collision implied that nothing could be done, and the
data was lost (unless one transmitter overwhelmed the other

What are you trying to get with 'ftw'? That's not a GNU Radio component.

Hi Tom,
I see, therefore it does not import. There is a project:
https://www.cgran.org/wiki/ftw80211ofdmtx
It installs FTW packages into gnuradio during installation. However it does
not import.

Hi Tom,
It runs under GRC when GRC is launched from a terminal but not when launched
from the desktop. So it's not getting the modified PYTHONPATH from
gnome-session. Looked for gnuradio-companion.desktop file to place a
PYTHONPATH, but couldn't find it.
Ultimately added ppa:borg/ppa to the

One further update: I played around with the SWIG provided includes for std,
and it seems possible to tweak them to allow GNU Radio to be fully usable on
10.9. It's something that needs to come from upstream (the SWIG folks), since
they need to #ifdef CXX11 or something around the code. But,
