comnum.dvbt_channel_gains(profile, frequencies)

The gains of the static channels of Annex B of EN 300 744 (DVB-T) at baseband frequencies: the fixed reception F1 (20 echoes and a direct path, Ricean factor 10 dB) and the portable reception P1 (the 20 echoes of Table B.1), normalised to a unit power gain.

Parameters:

• profile (str) – "F1" or "P1".

• frequencies (array_like) – the frequencies (Hz), e.g. Dvbt.carrier_frequencies().

Returns:

the gains H(f) (complex128).

Return type:

numpy.ndarray

Raises:

ValueError – for another profile.
