摘要：        Recently, with the explosive increase in communication traffics, there is a tremendous pressure on the data transmission over the wireless network. In order to effectively alleviate the wireless network load, coded caching scheme was proposed, and now is a hot topic in industrial and academic fields. In this talk, we first characterize coded caching scheme by a simple combinatorial concept, called placement delivery array (PDA in short). Then several new PDAs are obtained by combinatorial design theory and graph theory respectively. Consequently, the corresponding new coded caching schemes are obtained.
