This function inserts the given PSDU in a WifiConstPsduMap along with a STA-ID value that is determined based on whether the given PSDU has to be transmitted as a DL or UL frame, thus allowing to properly calculate the TX duration in case the PSDU has to be transmitted as an UL frame.

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.

Note: in order to properly model out of band transmissions for OFDM, the guard band has been configured so as to expand the modeled spectrum up to the outermost referenced point in "Transmit spectrum mask" sections' PSDs of each PHY specification of 802.11-2016 standard. It thus ultimately corresponds to the current channel bandwidth (which can be different from devices max channel width).
This method is only relevant for SpectrumWifiPhy.

Implemented for encapsulation purposes. This method will extract all MPDUs if packet is an A-MPDU and will fire tracedCallback. The A-MPDU reference number (RX side) is set within the method. It must be a different value for each A-MPDU but the same for each subframe within one A-MPDU.
| psdu | the PSDU being received |
| channelFreqMhz | the frequency in MHz at which the packet is received. Note that in real devices this is normally the frequency to which the receiver is tuned, and this can be different than the frequency at which the packet was originally transmitted. This is because it is possible to have the receiver tuned on a given channel and still to be able to receive packets on a nearby channel. |
| txVector | the TXVECTOR that holds RX parameters |
| signalNoise | signal power and noise power in dBm (noise power includes the noise figure) |
| statusPerMpdu | reception status per MPDU |
| staId | the STA-ID |
