Solution to Cover’s Problem in the Gaussian Case. Information Theory 60 Information Theory 64 2: Our approach is geometric and builds on an extension we develop for the isoperimetric inequality on a high-dimensional sphere.

A Geometric Approach to two Problems in Networks: Communication With Crystal-Free Radios. Fong , Vincent Y. Geometry of sets on the hamming sphere. On feedback in Gaussian multi-hop networks. Motivated by this trend, we consider the problem of estimating high-dimensional distributions and parameters in a distributed network, where each node in the network observes an independent sample from the underlying distribution and can communicate it to a central processor by writing at most k bits on a public blackboard. The geometry of the relay channel.

The cut-set bound developed by Cover and El Gamal in has since remained the best known upper bound on the capacity of the Gaussian relay channel. NSF names grads to research-funding The key ingredient in our proof is a geometric characterization of Fisher information from quantized samples.

We use measure concentration to analyze the probabilistic geometric relations between the typical sets of the n-letter random variables associated with a reliable code, which translate to new entropy inequalities between the random variables involved in the problem.
