https://github.com/git-artes/gr-isdbtJust replace the gr-dvbt ofdm_sym_acquisition block with the one from gr-isdbt. Leave the freq. error output unconnected.
I believe German DVB-T is 16QAM 2/3 rate, so your captured signal should be at least 12 dB to 15 dB above the noise, preferably more.
Also, since you're using a B210, you can use the correct DVB-T sample rate of (8,000,000 * 8) / 7 Msps (instead of 10 Msps) and delete the rational resampler block in the flow graph.

Hello all, I am trying to receive a DVB-T signal which I have recorded using a USRP B210.I have set all parameters correctly but I am unable to receive the output stream. I already verified that I have a spike at 746MHz which is the frequency of my broadcast station.i think the problem is with the synchronization. I am getting restart aquisition as my grc output continously. There are some messages before as well which I have attached as a screenshot. Anyone who could check where the error is? Thanks all very much. Regards Ahsan
