Please see Page 17, subsection IV-B, in the report
M. A. Maddah-Ali, A. S. Motahari, and Amir K. Khandani, "Communication over MIMO X Channels:
Signaling and Multiplexing Gain", Technical Report, UW-E&CE #2006-12“Overlap of the interference terms
at the receivers’ side”, which introduces the idea of ‘’Interference Alignment” for the first time.
