Getting the most out of your FFT
Abstract
The galaxies in our universe consist largely ofatomic hydrogen, which emits radiation at 21 cm.This radio signal was predicted by v.d. Hulst in 1944, and first detected by Ewen & Purcell in 1951. Nowadays, detecting the signature of the 21 cm radiation is well within the means of ama-teurs using simple means such as a small antenna, low-noise amplifier and a SDR. The hardware required for such experiments is well known. This presentation instead is focused on how the digitized signal can be processed for best sensitivity in the GNU Radio Companion.
