Local fidelity, constrained codes, and the Meru Prastara

Abstract

A relationship between the capacity and constrained codes for recording channels and rate distortion for sources with respect to context-dependent fidelity criteria in communication systems are used in the computation of other rate-distortion functions. The problem of optimal transmitter/receiver design is solved by evaluating the design of optimal source encoders and decoders for compression and the design of optimal channel encoders and decoders fro error protection. The coding-theorems of information theory show that the performance of optimal solutions to the source-coding and channel-coding problems can be expressed in terms of the rate distortion function and the capacity cost function. The desirable properties for distortion functions in communication systems include tractability, computability, and subjective significance.
