چکیده
We characterize the sum rate of a class of multiterminal Gaussian source coding problems with quadratic distortion constraints. The key component of the solution is the identification of a multiple antenna broadcast channel that serves as a test channel.

Sum-rate distortion bound for suboptimal multiterminal source coding applied in medical wireless sensor networks
In this paper, we derive the suboptimal sum-rate distortion bound for encoding correlated Gaussian sources for which the uniform scalar quantizers are used to convert the signals from analog to the discrete form. The correlated discrete signals are further compressed using the lossless Slepian and Wolf encoder. The gap between the suboptimal bound and the inner/outer bounds is also investigated...
متن کاملDistributed Source Coding of Correlated Gaussian Sources
We consider the distributed source coding system of L correlated Gaussian sources Yl, l = 1, 2, · · · , L which are noisy observations of correlated Gaussian remote sources Xk, k = 1, 2, · · · ,K. We assume that Y L = (Y1, Y2, · · · , YL) is an observation of the source vector X = (X1, X2, · · · , XK), having the form Y L = AX+N, where A is a L×K matrix and N = (N1, N2, · · · , NL) is a vector ...
متن کاملMultiterminal Source Coding with High Resolution
We consider separate encoding and joint decoding of correlated continuous information sources, subject to a difference distortion measure. We first derive a multiterminal extension of the Shannon lower bound for the rate region. Then we show that this Shannon outer bound is asymptotically tight for small distortions. These results imply that the loss in the sum of the coding rates due to the se...
متن کاملGeneralized Gaussian Multiterminal Source Coding: The Symmetric Case
Consider a generalized multiterminal source coding system, where ( l m ) encoders, each observing a distinct sizem subset of l (l ≥ 2) zero-mean unit-variance symmetrically correlated Gaussian sources with correlation coefficient ρ, compress their observations in such a way that a joint decoder can reconstruct the sources within a prescribed mean squared error distortion based on the compressed...
متن کاملRobust Distributed Source Coding with Arbitrary Number of Encoders and Practical Code Design Technique
The robustness property can be added to DSC system at the expense of reducing performance, i.e., increasing the sum-rate. The aim of designing robust DSC schemes is to trade off between system robustness and compression efficiency. In this paper, after deriving an inner bound on the rate–distortion region for the quadratic Gaussian MDC based RDSC system with two encoders, the structure of...
