Detailed Description

This class implements a gaussian interference model, i.e., all incoming signals are added to the total interference.

Definition at line 46 of file lte-interference.h.

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

Definition at line 250 of file lte-interference.cc.

References m_interfChunkProcessorList, and NS_LOG_FUNCTION.

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

p

Definition at line 236 of file lte-interference.cc.

References m_rsPowerChunkProcessorList, and NS_LOG_FUNCTION.

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

Definition at line 135 of file lte-interference.cc.

References NS_LOG_FUNCTION, and ns3::Simulator::Schedule().

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

Add a LteSinrChunkProcessor that will use the time-vs-frequency SINR calculated by this LteInterference instance. Note that all the added LteSinrChunkProcessors will work in parallel.

Parameters

p

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.

Definition at line 48 of file lte-interference.cc.

References ns3::Object::DoDispose(), m_allSignals, m_interfChunkProcessorList, m_rsPowerChunkProcessorList, m_rxSignal, m_sinrChunkProcessorList, and NS_LOG_FUNCTION.

void ns3::LteInterference::EndRx ( )

notify that the RX attempt has ended. The receiving PHY must call this method when RX ends or RX is aborted.

Definition at line 107 of file lte-interference.cc.

References m_interfChunkProcessorList, m_rsPowerChunkProcessorList, m_sinrChunkProcessorList, NS_LOG_FUNCTION, and NS_LOG_INFO.

void ns3::LteInterference::SetNoisePowerSpectralDensity ( Ptr< const SpectrumValue > noisePsd )

Parameters

noisePsd the Noise Power Spectral Density in power units (Watt, Pascal...) per Hz.

Definition at line 217 of file lte-interference.cc.

References m_allSignals, and NS_LOG_FUNCTION.

void ns3::LteInterference::StartRx ( Ptr< const SpectrumValue > rxPsd )

notify that the PHY is starting a RX attempt

Parameters

rxPsd the power spectral density of the signal being RX
