[moved to freebsd-chat] OFDM doesn't exist in the digital domain. The furthest you can go in software is to use the I-Q pairs that represent the modulated (baseband) data - that is, QPSK, BPSK, QAM etc. If you have a card that makes I-Q data accessible (and I suspect most wireless cards don't) then you can demodulate it using general-purpose software such as Matlab or a DSP library. -- Bruce Cran _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-chat To unsubscribe, send any mail to "[email protected]"
