Hello, In https://wireless.wiki.kernel.org/en/users/drivers/ath9k/spectral_scan and https://wiki.freebsd.org/dev/ath_hal%284%29/SpectralScan and a few mails on this list I have seen it stated that the FFT data for each bin is reported as the sum of the absolute magnitudes of both I and Q components, i.e, |i|+|q|. However, I have also seen the square of the returned bin value being directly plugged into the formula for estimating the bin power in numerous post-processing applications, which doesn't make sense for me. As power is calculated by i^2+q^2, which doesn't equal to (|i|+|q|)^2. Can anybody kindly clear this up for me? Thanks a lot.
Best wishes, Robert _______________________________________________ ath9k-devel mailing list ath9k-devel@lists.ath9k.org https://lists.ath9k.org/mailman/listinfo/ath9k-devel
