commit e4b89a11cb942ca0ee4bc7908457f2a5eae6848b Author: Sylvain Munaut tnt@246tNt.com Date: Sat Apr 4 22:53:44 2015 +0200

gr-gmr1: Switch the 'freq' tag to be in Hertz

This also required adapting the file_sink. It now has an option to specify if the spectrum was inverted or not. It's necessary to know if the received frequency has to be added or substracted from the center frequency.

gr-gmr1: Tighten the low_pass in gmr_rach_scan

30 kHz is more than enough and helps get rid of adjacent bursts better

gr-gmr1: Change freq_offset to peak_freq

This represents the frequency of the expected peak compared to the center of the burst. This is also the frequency at which the peak CW will end up at at the output.

commit 31394e9be9cd5839a5a2b04a828de9a701c65953 Author: Sylvain Munaut tnt@246tNt.com Date: Sat Apr 4 18:13:19 2015 +0200

gr-gmr1: Make rach_detect_fft use sample_rate instead of fft_size as param

The is really no reason to use any other fft size than the auto computed one and having the sample_rate will allow the output frequency to be in hz rather than radian.
