A general method of coding over expansion is proposed, which allows one to reduce the highly non-trivial problems of coding over analog channels and compressing analog sources to a set of much simpler subproblems, coding over discrete channels and compressing discrete sources. More specifically, the focus of this paper is on the additive exponential noise (AEN) channel, and lossy compression of...

We use mean-field theory methods from Statistical Mechanics to derive the "softmax" nonlinearity from the discontinuous winnertake-all (WTA) mapping. We give two simple ways of implementing "soft max" as a multiterminal network element. One of these has a number of important network-theoretic properties. It is a reciprocal, passive, incrementally passive, nonlinear, resistive multiterminal elem...

A source coding problem is considered for a robust description system with one encoder and many decoders. The rate-reliability-distortion function is specified. An example is given showing a distinction in calculation of the rate-reliability-distortion function as compared with the rate-distortion function.

In this paper, a robust image transmission scheme based on JPEG2000 is proposed for packet erasure channels. Error resilience functionalities provided by JPEG2000 are utilized to control the source coding efficiency and the robustness according to channel conditions. Furthermore, together with the proposed interleaving scheme, some erasures can be recovered. Experimental results show the effect...

The data sensed by different sensors in a sensor network is typically correlated. A natural question is whether the data correlation can be exploited in innovative ways along with network information transfer techniques to design efficient and distributed schemes for the operation of such networks. This necessarily involves a coupling between the issues of compression and networked data transmi...

We consider a scenario wherein two parties Alice and Bob are provided $X_{1}^{n}$ notation="LaTeX">$X_{2}^{n}$ – samples that IID from PMF notation="LaTeX">$P_{X_{1} X_{2}}$ . can communicate to Charlie over (noiseless) communication ...
