Thanks Doug. I took a sample dump at 25Msps using the USRP2 and have been pumping these samples through the decoder trying to get some output. I know for a fact there are 8 packets in the trace, but haven't been able to find any yet. Working on it :) - George On Sun, Nov 29, 2009 at 11:44 PM,

I also think that the decoder is improperly looking for synchronization... According to the 802.11 spec, the long preamble uses an SFD that is 0xF3A0, and the short is 0x05CF (verified by a quick google ( http://www.google.com/search?hl=en&safe=off&client=firefox-a&rls=org.mozilla%3Aen-US%3Aoffici

Hi all, For those of you who have worked closely with the BBN 802.11 code, does it only handle a long preamble? I have not been able to get it to successfully decode any of my packets, which are all using a short preamble. - George ___ Discuss-gnuradio
