Writing on Dirty Paper with Resizing and its Application to Quasi-Static Fading Broadcast Channels
— This paper studies a variant of the classical problem of “writing on dirty paper” in which the sum of the input and the interference, or dirt, is multiplied by a random var...

A Channel that Heats Up
Motivated by on-chip communication, a channel model is proposed where the variance of the additive noise depends on the weighted sum of the past channel input powers. For this chan...
