I was wondering what is this benchmark_add_channel.py for. Is it for
adding a
new channel “on the fly” to an ongoing OFDM transmission 
using verbose it says the format to run it as
./benchmark_add_channel.py [options]

The benchmark_add_channel.py (which are in both the ofdm and
narrowband examples) is designed to let people play with channel
properties in simulation. The benchmark_tx scripts have a --to-file
that saves all of the data into a local file instead of trying to use
a USRP to go over the air. Likewise, the benchmark_rx scripts have a
–from-file to read in the data from a file. The benchmark_add_channel
takes in the file and performs the operations that are specified (AWGN
noise power, frequency offset, timing offset, etc.) and outputs a new
file that can then be read in by the receive scripts.

Thanks Tom … That is really a useful thing 
Although this script is only in ofdm folder and not in the digital folder
but I guess the same can be used for both.
Glad that helps.
And it’s in both narrowband and ofdm:
