Detailed Description

Simple SpectrumPhy implementation that sends customizable waveform.

Introspection did not find any typical Config paths.

The generated waveforms have a given Spectrum Power Density and duration (set with the SetResolution()) . The generator activates and deactivates periodically with a given period and with a duty cycle of 1/2.

This PHY model supports a single antenna model instance which is used for both transmission and reception (though received signals are discarded by this PHY).

Attributes

DutyCycle: the duty cycle of the generator, i.e., the fraction of the period that is occupied by a signal
- Set with class: ns3::DoubleValue
- Underlying type: double -1.79769e+308:1.79769e+308
- Initial value: 0.5
- Flags: constructwriteread
Period: the period (=1/frequency)
- Set with class: ns3::TimeValue
- Underlying type: Time +9.22337e+18ns:+9.22337e+18ns
- Initial value: +1e+09ns
- Flags: constructwriteread

TraceSources

TxEnd: Trace fired when a previously started transmission is finished
Callback signature: ns3::Packet::TracedCallback
TxStart: Trace fired when a new transmission is started
Callback signature: ns3::Packet::TracedCallback

Size of this type is 176 bytes (on a 64-bit architecture).

Member Function Documentation

◆ DoDispose()

void ns3::WaveformGenerator::DoDispose ( )

overrideprivatevirtual

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 overridden 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.
