Web17 de out. de 2024 · This monograph provides a broad overview of this fascinating subject, focusing on the simplest form of multiple-unicast index coding. The main objective in studying the index coding problem are to characterize the capacity region for a general index coding instance in a computable expression and to develop the coding scheme … Webserver broadcast rates, which is defined formally as the capacity region, is studied for a general distributed index coding problem. Inner and outer bounds on the capacity region are established that have matching sum-rates for all 218 non-isomorphic four-message problems with equal link capacities for all the links from servers to receivers.
