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.

Prepare 3gpp channel parameters among the nodes a and b.
The function does the following steps described in 3GPP 38.901:
Step 4: Generate large scale parameters. All LSPS are uncorrelated. Step 5: Generate Delays. Step 6: Generate cluster powers. Step 7: Generate arrival and departure angles for both azimuth and elevation. Step 8: Coupling of rays within a cluster for both azimuth and elevation shuffle all the arrays to perform random coupling Step 9: Generate the cross polarization power ratios Step 10: Draw initial phases
All relevant generated parameters are added then to ThreeGppChannelParams which is the return value of this function.

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.
