On the Sum Secure Degrees of Freedom of Two-Unicast Layered Wireless Networks
The authors consider a two-unicast layered network where two transmitters wish to have reliable and secure communication with their respective receivers simultaneously, by utilizing a layered network between the transmitters and receivers. The single-layer version of this network is an interference channel, whose capacity is unknown in general; it is known only in certain special cases, e.g., a class of deterministic interference channels, a class of strong interference channels, a class of degraded interference channels. The degrees of freedom (d.o.f.) characterizations have been found for the interference channel in several different settings.
