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.
