Coded Caching Schemes With Linear Subpacketizations [PDF]
IEEE Transactions on Communications, 2021 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.

Optimum subpacket transmission for hybrid ARQ systems [PDF]
IEEE Transactions on Communications, 2006 Hybrid automatic-repeat-request (ARQ) is a flexible and efficient technique for data transmissions. In hybrid ARQ, subpacket schemes are more attractive for systems with burst errors than complete packet schemes. Although subpacket schemes were proposed in ARQ systems, optimum subpacket transmission is more effective to maximize throughput in a dynamic

Multi-access Coded Caching with Linear Subpacketization
2023 IEEE International Symposium on Information Theory (ISIT), 2023 We consider the multi-access coded caching problem, which contains a central server with $N$ files, $K$ caches with $M$ units of memory each and $K$ users where each one is connected to $L (\geq 1)$ consecutive caches, with a cyclic wrap-around. Caches are populated with content related to the files and each user then requests a file that has to be ...

Coded Caching with Polynomial Subpacketization
CoRR, 2020 Consider a centralized caching network with a single server and $K$ users. The server has a database of $N$ files with each file being divided into $F$ packets ($F$ is known as subpacketization), and each user owns a local cache that can store $\frac{M}{N}$ fraction of the $N$ files.

Evolution of Chorus Subpackets in the Earth's Magnetosphere
Geophysical Research Letters, 2023 AbstractChorus subpackets/subelements are the wave packets occurring at intervals of ∼10–100 msec and are suggested to play a crucial role in the formation of substructures within pulsating aurora. In this study, we investigate the evolution of subpackets from the upstream to downstream regions.

Low-Subpacketization Multi-Antenna Coded Caching for Dynamic Networks
2022 Joint European Conference on Networks and Communications & 6G Summit (EuCNC/6G Summit), 2022 Multi-antenna coded caching combines a global caching gain, proportional to the total cache size in the network, with an additional spatial multiplexing gain that stems from multiple transmitting antennas. However, classic centralized coded caching schemes are not suitable for dynamic networks as they require prior knowledge of the number of users to ...

Symmetric uncoded caching schemes with low subpacketization levels
CoRR, 2020 Caching is a commonly used technique in content-delivery networks which aims to deliver information from hosting servers to users in the most efficient way. In 2014, Maddah-Ali and Niessen formulated caching into a formal information theoretic problem and it has gained a lot of attention since then.

A Low-Subpacketization High-Performance MIMO Coded Caching Scheme
CoRR, 2021 In this paper, we study how coded caching can be efficiently applied to multiple-input multiple-output (MIMO) communications. This is an extension to cache-aided multiple-input single-output (MISO) communications, where it is shown that with an $L$-antenna transmitter and coded caching gain $t$, a cumulative coded caching and spatial multiplexing gain ...

Subpacketization-Rate Trade-Off in Multi-Antenna Coded Caching [PDF]
2019 IEEE Global Communications Conference (GLOBECOM), 2019 Coded caching can be applied in wireless multi-antenna communications by multicast beamforming coded data chunks to carefully selected user groups and using the existing file fragments in user caches to decode the desired files at each user. However, the number of packets a file should be split into, known as subpacketization, grows exponentially with ...
