Re: [ath9k-devel] linearity of ath9k CSI phase

Dear Joe Ayers Thanks for your response again. I started studying and investigating on antennas theories. Regards, Jeon. 2016-06-14 14:19 GMT+09:00 Joe Ayers : > This increased spacing looks to impact the detection angle before aliasing > occurs with grating lobes. Google

Re: [ath9k-devel] linearity of ath9k CSI phase

Dear Joe Ayers, Thank you for response. I don't have a sort of RF anechoic chamber. So, I've captured CSI in a quite realistic and practical environemnt with possible interference and multipath components. There are other WLAN APs, Bluetooth devices. Also, there exist desks, chairs and walls as

[ath9k-devel] linearity of ath9k CSI phase

Dear ath9k developers, I am currently working with Atheros CSI Extraction Tool [1] to get a true phase of each subcarrier. - Background [2], [3] and many other papers claim that phase information from extracted CSI contains two components: true phase and unwanted phase offset due to subcarrier
