Detailed Description

Simple SpectrumPhy implemetation that averages the spectrum power density of incoming transmissions to produce a spectrogram.

Introspection did not find any typical Config paths.

This PHY model supports a single antenna model instance which is used for reception (this PHY model never transmits).

Attributes

Resolution: The lengh of the time interval over which the power spectral density of incoming signals is averaged
- Set with class: ns3::TimeValue
- Underlying type: Time –9223372036854775808.0ns:+9223372036854775807.0ns
- Initial value: +1000000.0ns
- Flags: construct write read
NoisePowerSpectralDensity: The power spectral density of the measuring instrument noise, in Watt/Hz. Mostly useful to make spectrograms look more similar to those obtained by real devices. Defaults to the value for thermal noise at 300K.
- Set with class: ns3::DoubleValue
- Underlying type: double -1.79769e+308:1.79769e+308
- Initial value: 4.14e-21
- Flags: construct write read

TraceSources

AveragePowerSpectralDensityReport: Trace fired whenever a new value for the average Power Spectral Density is calculated
Callback signature: ns3::SpectrumValue::TracedCallback

Size of this type is 136 bytes (on a 64-bit architecture).

Destructor implementation.

This method is called by Dispose() or by the Object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overriden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.

It is safe to call GetObject() from within this method.

Reimplemented from ns3::Object.
