torchsig.signals.builders.fsk.get_fsk_mod_index(class_name: str, rng=Generator(PCG64) at 0x7694C485E880) → float[source]

FSK modulation index.

The modulation index is a parameter that is derived from the symbol spacing in the frequency domain. Orthogonal FSK has a modulation index of 1.0, and MSK and GMSK have a modulation index of 0.5. The modulation index is randomized over a wide range for both GFSK and FSK.

Parameters:

  • class_name (str) – Class name to return modulation index, ex: ‘2fsk’.

  • rng (optional) – Seedable random number generator for reproducibility.

Returns:

Modulation index.

Return type:

float
