Member Function Documentation

void ns3::LteInterference::AddInterferenceChunkProcessor ( Ptr< LteSinrChunkProcessor > p )

Add a LteSinrChunkProcessor that will use the time-vs-frequency interference calculated by this LteInterference instance.

Note that all the added LteSinrChunkProcessors will work in parallel.

Parameters

p

void ns3::LteInterference::AddRsPowerChunkProcessor ( Ptr< LteSinrChunkProcessor > p )

Add a LteSinrChunkProcessor that will use the time-vs-frequency power calculated by this LteInterference instance.

Note that all the added LteSinrChunkProcessors will work in parallel.

Parameters

void ns3::LteInterference::AddSignal	(	Ptr< const SpectrumValue >	spd,
		const Time	duration
	)

notify that a new signal is being perceived in the medium.

This method is to be called for all incoming signal, regardless of wether they're useful signals or interferers.

Parameters

spd	the power spectral density of the new signal
duration	the duration of the new signal

void ns3::LteInterference::DoDispose ( void )

virtual

This method is called by Object::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.
