Message-ID: <52319F39.1040104@uth.gr> (raw)
Hi all,
lately I am studing the Atheros Spectral Scan feature and I am using
Atheros 9380 and compat-drivers-3.9-rc4-2-su for doing this.
When you trigger a Spectral Scan the file
/sys/kernel/debug/ieee80211/phy0/ath9k/spectral_scan0 is created.
Is the hardware responsible for something other than collecting
samples? Is there any circuit which performs the FFT procedure after
collecting the samples or just this process is done by driver? Could
you give me some more details about the whole FFT procedure?
Thank you in advance
Kostas
