◆ DoDispose()

void ns3::ThreeGppChannelModel::DoDispose ( void  )
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.

◆ GetChannel()

Ptr< const MobilityModel >  bMob,
Ptr< const ThreeGppAntennaArrayModel >  aAntenna,
Ptr< const ThreeGppAntennaArrayModel >  bAntenna 
)
overridevirtual

Looks for the channel matrix associated to the aMob and bMob pair in m_channelMap.

If found, it checks if it has to be updated. If not found or if it has to be updated, it generates a new uncorrelated channel matrix using the method GetNewChannel and updates m_channelMap.

Parameters
aMobmobility model of the a device
bMobmobility model of the b device
aAntennaantenna of the a device
bAntennaantenna of the b device
Returns
the channel matrix
