Phase Noise¶
Phase noise refers to the effect random fluctuations in a non-ideal osciallators phase have on a signal modulated by that osicallator. The effect of phase noise is to spread the signal out in the frequency domain. The currently implemented phase noise models are
Phase Noise Model |
Description |
|---|---|
No phase noise is added to the signal. |
|
Phase noise is added to the signal based on its freuency domain characteristics. |
Configuring a SimulatedDevice's phase noise model
requires setting the phase_noise property
of the device’s rf_chain:
1# Create a new device
2simulation = Simulation()
3device = simulation.new_device()
4
5# Configure the device's default phase noise model
6device.rf_chain.phase_noise = PhaseNoise()
Of course, the abstract PhaseNoise model in the above snippet has to be replaced by one the implementations listed above.
- class PhaseNoise(mother_node=None, seed=None)[source]¶
Bases:
RandomNode,ABCBase class of phase noise models.
- Parameters:
mother_node (RandomNode, optional) – Mother node of this random node. By default, nodes are considered to be roots.
seed (int, optional) – Random seed used to initialize the pseudo-random number generator.
