MaxLossDb: If a single-frequency PropagationLossModel is used, this value represents the maximum loss in dB for which transmissions will be passed to the receiving PHY. Signals for which the PropagationLossModel returns a loss bigger than this value will not be propagated to the receiver. This parameter is to be used to reduce the computational load by not propagating signals that are far beyond the interference range. Note that the default value corresponds to considering all signals for reception. Tune this value with care.

No TraceSources are defined for this type.

TraceSources defined in parent class ns3::SpectrumChannel

Gain: This trace is fired whenever a new path loss value is calculated. The parameters to this trace are : Pointer to the mobility model of the transmitterPointer to the mobility model of the receiverTx antenna gainRx antenna gainPropagation gainPathloss
Callback signature: ns3::SpectrumChannel::GainTracedCallback
PathLoss: This trace is fired whenever a new path loss value is calculated. The first and second parameters to the trace are pointers respectively to the TX and RX SpectrumPhy instances, whereas the third parameters is the loss value in dB. Note that the loss value reported by this trace is the single-frequency loss value obtained by evaluating only the TX and RX AntennaModels and the PropagationLossModel. In particular, note that SpectrumPropagationLossModel (even if present) is never used to evaluate the loss value reported in this trace.
Callback signature: ns3::SpectrumChannel::LossTracedCallback
TxSigParams: This trace is fired whenever a signal is transmitted.The sole parameter is a pointer to a copy of the SpectrumSignalParameters provided by the transmitter.
Callback signature: ns3::SpectrumChannel::SignalParametersTracedCallback

Member Function Documentation

◆ AddRx()

void ns3::SingleModelSpectrumChannel::AddRx ( Ptr< SpectrumPhy > phy )

virtual

Add a SpectrumPhy to a channel, so it can receive packets.

This method is used to attach a SpectrumPhy instance to a SpectrumChannel instance, so that the SpectrumPhy can receive packets sent on that channel. Note that a SpectrumPhy that only transmits (without receiving ever) does not need to be added to the channel.

This method is to be implemented by all classes inheriting from SpectrumChannel.

Parameters

phy	the SpectrumPhy instance to be added to the channel as a receiver.

Implements ns3::SpectrumChannel.

◆ DoDispose()

void ns3::SingleModelSpectrumChannel::DoDispose ( void )

privatevirtual

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::SpectrumChannel.
