| Abstract(in English) | Index coding for sharing information via satellite communication is considered. Each receiver knows some of the messages a priori, and the sender encodes the messages using all receivers' prior information and requirements. We propose graph representations for index coding problems where the receivers' prior information does not overlap. Using these graph representations, minimum codelength is clarified for the problem where the receivers require single message. Furthermore, upper and lower bounds on the minimum codelength are shown for the problem where the receivers require multiple messages. |
