Detailed Description

This minimal SpectrumPhy implementation calculates the SINR with respect to the strongest signal for a given point.

The original purpose of this class is to be used to generate a Radio Environment Map (REM) by locating several instances in a grid fashion, and connecting them to the channel only for a very short amount of time.

The assumption on which this class works is that the system being considered is an infrastructure radio access network using FDD, hence all signals will be transmitted simultaneously.

Member Function Documentation

◆ Deactivate()

void ns3::RemSpectrumPhy::Deactivate ( )

make StartRx a no-op from now on, and mark instance as inactive

Definition at line 181 of file rem-spectrum-phy.cc.

References m_active.

◆ DoDispose()

void ns3::RemSpectrumPhy::DoDispose ( )

overridevirtual

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::Object.
