Re: [Discuss-gnuradio] 802.11a source codes? or any OFDM implementation on GNU Radio

[Mohsen Baratvand]

Guy, all I need to do is changing some parameters such as preamble, LTF, STF, modulation and etc of the OFDM transmitter and then send a predefined pattern to the OFDM receiver, then estimate the channel. So I'm not gonna pass all the information and data to PC via the USB link. Just sending some report to my PC.

That code does implement an 802.11b receiver, and a transmitter that is very similar to 802.11b (since the USRP is limited by the USB bandwidth it can't really do real 802.11b - without doing some of the work in the FPGA at least).  However, that's all DSSS using a DBPSK/DQPSK modulation scheme - not OFDM (or even the 5.5Mbps and 11Mbps CCK data rates).  Perhaps with the USRP2 - which will be able to do full-bandwidth 802.11b/g someone will start that (perhaps I will even contribute to such work...).

   Hi everyone,

   Does anyone know if there is any source code available for OFDM
   type standards like 802.11a/g/n?
   I'd appreciate it if anybody knows.

   Thanks a lot,
   Mohsen
