Rate Compatible Modulation for Correlated Information Sources

Zero-Error Codes for Correlated Information Sources

Stepian and W~olf [2] gave a characterization for the compression region of distributed correlated sources. Their result is for codes with a decoding probability of error approaching zero as the code length is increased. Of interest in many applications is to find codes for which the probability of error is exactly zero. For this latter case, block codes using the zero-error information between...

Noiseless coding of correlated information sources

A new class of lower bounds to rate-distortion functions ofstationary processes with memory and single-letter vector-valued distor-tion measures is derived. This class is shown to include or imply all otherwell-known lower bounds to rates of such sources and distortion measures.The derivation is based on the definition and properties of the conditionalratedistortion function...

Blind Separation of Jointly Stationary Correlated Sources

The separation of unobserved sources from mixed observed data is a fundamental signal processing problem. Most of the proposed techniques for solving this problem rely on independence or at least uncorrelation assumption for source signals. This paper introduces a technique for cases that source signals are correlated with each other. The method uses Wold decomposition principle for extracting ...

An efficient CDMA decoder for correlated information sources

We consider the detection of correlated information sources in the ubiquitous Code-Division Multiple-Access (CDMA) scheme. We propose a messagepassing based scheme for detecting correlated sources directly, with no need for source coding. The detection is done simultaneously over a block of transmitted binary symbols (word). Simulation results are provided demonstrating a substantial improvemen...
