Member Function Documentation

◆ CreateTxPowerSpectralDensity()

virtual Ptr<SpectrumValue> ns3::LtePhy::CreateTxPowerSpectralDensity ( )

pure virtual

Compute the TX Power Spectral Density.

Returns: a pointer to a newly allocated SpectrumValue representing the TX Power Spectral Density in W/Hz for each Resource Block

Implemented in ns3::LteTestUePhy, ns3::LteUePhy, and ns3::LteEnbPhy.

◆ DoDispose()

void ns3::LtePhy::DoDispose ( void )

virtual

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.

Reimplemented from ns3::Object.
