Hello Marcus, You sent the forwarded email a few months ago. The benchmark stuff doesn't, as far as I know, have FEC in it. I think Tom was referring to single-bit errors in the so-called "accesscode" at the beginning of the frame. If there are bit errors there, then the frame is necessarily

That sounds right to me too. Look at these files to get an idea: $GR/gnuradio-core/src/python/gnuradio/blks2impl/pkt.py $GR/gnuradio-core/src/python/gnuradio/packet_utils.py $GR/gnuradio-core/src/python/gnuradio/src/lib/general/gr_correlate_access_code_bb.cc $GR/gnuradio-examples/python/digital/re

Hello Tom, Marcus and Martin, Thanks a lot for your replies. One of the objective of our experiment is find to the capacity of a path, i.e, we want to transmit a random binary sequence between two USRP nodes. We want to find the maximum data transfer rate (in bit/sec) with a "small" bit error rate
