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 transmission during the peak traffic times). Placement delivery arrays (PDA) can be used to design code caching schemes. In this article we propose a framework of constructing PDAs via Hamming distance. As an application, two classes of coded caching schemes with linear subpacketizations and small transmission rates are obtained.

具有线性子分组化的编码缓存方案

在编码缓存系统中，我们更喜欢设计一种子分组化率低、传输速率小（即实现复杂度低、流量高峰时段传输效率高）的编码缓存方案。布局传递数组 (PDA) 可用于设计代码缓存方案。在本文中，我们提出了一个通过汉明距离构建 PDA 的框架。作为应用，获得了两类具有线性子分组化和小传输速率的编码缓存方案。
