Currently, I’m in Hong Kong to present my demo Power Matters: Automatic Gain Control for a Software Defined Radio IEEE 802.11a/g/p Receiver at IEEE INFOCOM’15.
I took a projector with me to provide a good view on the outputs that visualize the WiFi signal at different stages of the decoding process. The demo was setup on a small floor between the rooms where the technical sessions were held. So I think it gained some good visibility, especially during the coffee break.
With Automatic Gain Control (AGC) we have the last building block needed for conducting measurements on the road. We implemented AGC on the FPGA of a N210 with a XCVR2450 daugtherboard. I put a small video on YouTube that shows the power level with and without AGC.
Looking forward to test everything on the road :-)
