FCCH Bursts Detector
author
Piotr Krysik
description
Detects positions of FCCH bursts. At the end of each detected FCCH burst adds to the stream a tag with key "fcch" and value which is a frequency offset estimate. The input sampling frequency should be integer multiply of GSM GMKS symbol rate - 1625000/6 Hz.
