Member Function Documentation

void ns3::SpectrumInterference::AbortRx ( )

notify that the PHY has aborted RX

Here is the caller graph for this function:

void ns3::SpectrumInterference::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

protectedvirtual

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.

Here is the caller graph for this function:

bool ns3::SpectrumInterference::EndRx ( )

notify that the RX attempt has ended.

The receiving PHY must call this method upon RX end in order to: 1) know if RX was successful or not 2) free up resources that might eventually be used for the calculation of interference. Note that for this reason this method must also be called when RX is aborted.
