Abstract

Design of the optimal encoder and decoder for a discrete memoryless channel is a well-studied problem in classic information theory. However, there exists important systems which operate with components (encoder and decoders) that are prebuilt and possibly mismatched, limiting the achievable performance metrics. In this paper, we propose a model that takes into account such constraints. Using this model, we develop an understanding of the source coding problem in this context and introduce two new functions -transitory and restricted rate distortion- and analyze certain properties of them. In addition, one important application of this model for developing a comprehensive theory of semantic communication is discussed. Finally, some numerical examples are provided to illustrate the concepts mentioned in the paper.
