Explicit and almost sure conditions for K/2 degrees of freedom
Explicit and almost sure conditions for K/2 degrees of freedom
It is well known that in K-user constant single-antenna interference channels K/2 degrees of freedom (DoF) can be achieved for almost all channel matrices. Explicit conditions on the channel matrix to admit K/2 DoF are, however, not available. The purpose of this paper is to identify such explicit conditions, which …
