torchsig.transforms.functional.fading

torchsig.transforms.functional.fading(data: ndarray, coherence_bandwidth: float, power_delay_profile: ndarray, rng: Generator) → ndarray

Apply fading channel to signal. Currently only does Rayleigh fading.

Taps are generated by interpolating and filtering Gaussian taps.

Parameters:

• data – IQ data.

• coherence_bandwidth – coherence bandwidth relative to sample rate [0, 1.0].

• power_delay_profile – power delay profile assign to channel.

• rng – Random Generator to use. Defaults to None (new generator created internally).

Returns:

IQ data with fading applied.
