Combinatorial Analysis of Coded Caching Schemes

Ruizhong Wei

Coded caching schemes are used to reduce computer network traffics in peak time. To determine the efficiency of the schemes, \cite{MN} defined the information rate of the schemes a…

Coded Caching Schemes with Linear Subpacketizations

Xi Zhong, Minquan Cheng, Ruizhong Wei

In coded caching system we prefer to design a coded caching scheme with low subpacketization and small transmission rate (i.e., the low implementation complexity and the efficient…
