typedef std::vector<FadingTraceSample> ns3::TraceFadingLossModel::FadingTrace

private

Vector collecting the time fading traces in the frequency domain (per RB)

Definition at line 111 of file trace-fading-loss-model.h.

typedef std::vector<double> ns3::TraceFadingLossModel::FadingTraceSample

Member Function Documentation

int64_t ns3::TraceFadingLossModel::AssignStreams ( int64_t stream )

Assign a fixed random variable stream number to the random variables used by this model. Return the number of streams (possibly zero) that have been assigned.

Parameters

stream first stream index to use

Returns: the number of stream indices assigned by this model

Definition at line 224 of file trace-fading-loss-model.cc.

Ptr< SpectrumValue > ns3::TraceFadingLossModel::DoCalcRxPowerSpectralDensity	(	Ptr< const SpectrumValue >	txPsd,
		Ptr< const MobilityModel >	a,
		Ptr< const MobilityModel >	b
	)		const

privatevirtual

Parameters

txPower	set of values vs frequency representing the transmission power. See SpectrumChannel for details.
a	sender mobility
b	receiver mobility

Returns: set of values vs frequency representing the received power in the same units used for the txPower parameter.

Implements ns3::SpectrumPropagationLossModel.

void ns3::TraceFadingLossModel::DoInitialize ( void )

virtual

This method is called only once by Object::Initialize. If the user calls Object::Initialize multiple times, DoInitialize is called only the first time.

Subclasses are expected to override this method and chain up to their parent's implementation once they are done. It is safe to call GetObject and AggregateObject from within this method.

Reimplemented from ns3::Object.

Definition at line 106 of file trace-fading-loss-model.cc.

double ns3::TraceFadingLossModel::GetValue	(	int	subChannel,
		double	speed
	)

private

Get the value for a particular sub channel and a given speed.

Parameters

subChannel	the sub channel for which a value is requested
speed	the relative speed of the two devices

Returns: the loss for a particular sub channel
