optic.dsp.core.phaseNoise

phaseNoise(lw, Nsamples, Ts, seed=None)

Generate realization of a random-walk phase-noise process.

Parameters:

• lw (scalar) – laser linewidth.

• Nsamples (scalar) – number of samples to be draw.

• Ts (scalar) – sampling period.

• seed (int, optional) – Seed for the random number generator.

Returns:

phi – realization of the phase noise process.

Return type:

np.array
