We are experimenting with ofdm transmission and reception. We are
using benchmark_tx.py and benchmark_rx.py for transmission and reception
the examples folder of gnuradio (
/usr/local/share/gnuradio/examples/digital/ofdm). We are able to
and receive succesfully. Tracing the benchmark programs that we
above, we found that it uses the ofdm.py program located at (
However, we see that there is another implementation of ofdm in
ofdm_txrx.py and ofdm_receiver.py.
What is the difference between the two sets of implementations?
Why is the ofdm_txrx.py a hierarchial block?
