◆ 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.

		Ptr< const PhasedArrayModel >	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

aMob	mobility model of the a device
bMob	mobility model of the b device
aAntenna	antenna of the a device
bAntenna	antenna of the b device

Returns: the channel matrix

Wrap an (azimuth, inclination) angle pair in a valid range.

Specifically, inclination must be in [0, M_PI] and azimuth in [0, 2*M_PI). If the inclination angle is outside of its range, the azimuth angle is rotated by M_PI. This methods aims specifically at solving the problem of generating angles at the boundaries of the angle domain, specifically, generating angle distributions close to inclinationRad=0 and inclinationRad=M_PI.

Parameters

azimuthRad	the azimuth angle in radians
inclinationRad	the inclination angle in radians

Returns: the wrapped (azimuth, inclination) angle pair in radians
