Hi, I'm trying to create a wi-fi transmitter in GNURadio that can take a file source and transmit it as an 802.11 packet. I'm using this <https://github.com/bastibl/gr-ieee802-11/blob/maint-3.8/examples/wifi_tx.grc> example as a basis, and trying to follow the guides here <https://www.gnuradio.org/doc/doxygen/page_packet_data.html>.
Frankly, though, a lot of what's in that guide goes way over my head. I have a general understanding of what OFDM is, but my wi-fi packet receiver works just dandy without any OFDM blocks. So is it still necessary to incorporate such blocks into a transmitter? Secondly, I can't just plug a .pcap file source into the transmitter; it doesn't generate, and I get the feeling that .pcap isn't the proper format for transmission anyways. How can I figure out which blocks to put after the file source to make it gel with the next block in the example (WiFi MAC)?
