[Discuss-gnuradio] how to load data in payload of send_pkt in benchmark_ofdm_tx.py, and check with benchmark_ofdm_rx.py?

[James Park]

Hi,

 

I am confusing with send_pkt and payload.

How can i load the data that I want to transmit in the packet? and compare with received data using benchmark_ofdm_rx.py?

what I tried is adding file_sink to compare the transmit and the receive data, but it seems I can do more with send_pkt.

Also, would it be possible to choose one subcarrier that I want to use among others?

Thank you for your kine help.

 

James,
