AW: [Discuss-gnuradio] Impulse response in DVB-T, someboby knows how to

[Dobler, Anton]

Either you may go for a sequence, for example CAZAC or PN-sequences, that, if you cross-correlate the receive signal with the transmitted, show you the channel impulse response. 

The cross-correlation can be done in frequency domain using the properties of Fourier transformation. 

The easier approach if you just want to identify if there are other frequency components in your receive signal is to apply a FFT and have a look at the spectrum.

Best regards

It is too complicated for me right now to understand or measure a gnuradio block. However, I have seen in the oscilloscope the audio output of a continuous pilot and it looks like a sine wave.

The question could be: Can the components of that sine wave be separated in the time domain and thus know if there are different waves reaching the receiver?
