Improving Placement Delivery Array Coded Caching Schemes With Coded Placement [PDF]
IEEE Access, 2020 Coded caching schemes with low subpacketization and small transmission rate are desirable in practice due to the requirement of low implementation complexity and efficiency of transmission. Placement delivery arrays (PDA in short) can be used to generate

Combination Network with Multiaccess Caching [PDF]
EntropyIn the traditional (H,r,M,N) combination network, a central server storing N files communicates with K=(Hr) users through H cache-less relays. Each user has a local cache of size M files and is connected to a distinct subset of r relays.

Placement Delivery Array Design Through Strong Edge Coloring of Bipartite Graphs [PDF]
IEEE Communications Letters, 2018 The technique of coded caching proposed by Madddah-Ali and Niesen is a promising approach to alleviate the load of networks during busy times. Recently, placement delivery array (PDA) was presented to characterize both the placement and delivery phase in a single array for the centralized coded caching algorithm.

Centralized Hierarchical Coded Caching Scheme for Two-Layer Network [PDF]
EntropyThis paper considers a two-layer hierarchical network, where a server containing N files is connected to K1 mirrors and each mirror is connected to K2 users. Each mirror and each user has a cache memory of size M1 and M2 files, respectively.

Placement Delivery Array Design for Coded Caching Scheme in D2D Networks [PDF]
IEEE Transactions on Communications, 2019 Ji et al. (IEEE Transactions on Information Theory, 62(2): 849–869, 2016) first studied coded caching in device-to-device (D2D) networks, and proposed a D2D coded caching scheme, which is referred to as the JCM scheme. In practice, we prefer to design a scheme with its two important targets, i.e., the rate (the maximal total amount of transmission ...

Extended Placement Delivery Arrays for Multi-Antenna Coded Caching Scheme
2022 IEEE International Symposium on Information Theory (ISIT), 2022 The multi-antenna coded caching problem, where the server having $L$ transmit antennas communicating to $K$ users through a wireless broadcast link, is addressed. In the problem setting, the server has a library of $N$ files, and each user is equipped with a dedicated cache of capacity $M$. The idea of extended placement delivery array (EPDA), an array

IEEE Transactions on Communications, 2022 Coded caching is an emerging technique to reduce the data transmission load during the peak-traffic times. In such a scheme, each file in the data center or library is usually divided into a number of packets to pursue a low broadcasting rate based on the designed placements at each user's cache.
