Most communication systems use some form of feedback, often related to channel state information. The common models used in analyses either assume perfect channel state information...
This paper considers recovery of jointly sparse multichannel signals from incomplete measurements. Several approaches have been developed to recover the unknown sparse vectors from...
Motivated by a recent surge of interest in convex optimization techniques, convexity/concavity properties of error rates of the maximum likelihood detector operating in the AWGN ch...
Abstract--Memories whose storage cells transit irreversibly between states have been common since the start of the data storage technology. In recent years, flash memories have bec...
We consider three capacity definitions for composite channels with channel side information at the receiver. A composite channel consists of a collection of different channels with...
