George, You were talking about using m-blocks, along with doing more processing on the USRP (matched filter + dependent packet generator) in the FPGA, correct? The basic functionality of m-blocks is to be integrated into the main API as I understand (in a modified form perhaps?), and they do stil

Hi all, I would like to send a MAC layer control packet every 4 ms from computer A to computer B to tell B when to send data using USRP and GNU Radio.  It is like TDMA and a frame is 4 ms. I am trying to do this work by modifying tunnel.py in the gnuradio-example folder. I removed the carry sensin
