Degrees of freedom in vector interference channels
David Stotz, Helmut Bölcskei
This paper continues the Wu-Shamai-Verdu program [3] on characterizing the degrees of freedom (DoF) of interference channels (ICs) through Renyi information dimension. Specifically…

Capacity Pre-Log of Noncoherent SIMO Channels via Hironaka's Theorem
Veniamin I. Morgenshtern, Erwin Riegler, Wei Yang +4
We find the capacity pre-log of a temporally correlated Rayleigh block-fading SIMO channel in the noncoherent setting. It is well known that for block-length L and rank of the chan…
