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 example as a basis, and trying to follow the guides
here.
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)?
Thanks!
