A theory of multi-layer flat refractive geometry
Flat refractive geometry corresponds to a perspective camera looking through single/multiple parallel flat refractive mediums. We show that the underlying geometry of rays corres...

An Asymptotically Sum-Rate Optimal Precoding Scheme for MIMO Gaussian Broadcast Channel
—In this paper, we study the downlink precoding schemes for MIMO Gaussian broadcast channels (MIMO GBC). A novel low-complexity zero-forcing dirty-paper-coding (DPC) scheme, name...
