On the capacity region for index coding
TL;DR: A new inner bound on the capacity region of the general index coding problem is established, which relies on a random coding scheme and optimal decoding, and has a simple polymatroidal single-letter expression.
Journal ArticleDOI
The transition between the niche and neutral regimes in ecology.
Charles K. Fisher,Pankaj Mehta +1 more
TL;DR: Using two different theoretical models of ecological dynamics, it is shown that there is a transition in diverse ecological communities between a selection-dominated regime (the niche phase) and a drift-dominated regimes (the neutral phase), which is analogous to the phase diagram of water.
Proceedings ArticleDOI
Randomized sketches of convex programs with sharp guarantees
TL;DR: This work analyzes RP-based approximations of convex programs, in which the original optimization problem is approximated by the solution of a lower-dimensional problem, and proves that the approximation ratio of this procedure can be bounded in terms of the geometry of constraint set.
Proceedings ArticleDOI
On hypercontractivity and a data processing inequality.
TL;DR: This paper provides the correct tight constant to a data-processing inequality claimed by Erkip and Cover and turns out to be a particular hypercontractivity parameter of (X,Y), rather than their squared maximal correlation.
Journal ArticleDOI
Polar-Coded Non-Orthogonal Multiple Access
TL;DR: The block error ratio and throughput performances indicate that the proposed PC-NOMA systems obviously outperform the state-of-the-art turbo-coded N OMA systems due to the advantages of joint design between the polar coding and the NOMA transmission.

On the Capacity Region for Index Coding
TL;DR: In this paper, the capacity region of a general index coding problem with up to five messages was shown to have a polymatroidal single-letter expression, based on a random coding scheme and optimal decoding.
