Low subpacketization schemes for coded caching
2017 IEEE International Symposium on Information Theory (ISIT), 2017Coded caching is a technique that generalizes conventional caching and promises significant reductions in traffic over caching networks. However, the basic coded caching scheme requires that each file hosted in the server be partitioned into a large number (called the subpacketization level) of non-overlapping subfiles.

A Novel Framework for Coded Caching via Cartesian Product with Reduced Subpacketization
2022 IEEE International Symposium on Information Theory (ISIT), 2022 Caching prefetches some library content at users' memories during the off-peak times (i.e., {\it placement phase}), such that the number of transmissions during the peak-traffic times (i.e., {\it delivery phase}) are reduced. A coded caching strategy was originally proposed by Maddah-Ali and Niesen (MN) leading to a multicasting gain compared to the ...

A Probabilistic Subpacket Retransmission Scheme for ARQ Protocols
2008 IEEE International Conference on Communications, 2008A recent study demonstrated that the technique of subpacket retransmission can substantially improve the throughput of an ARQ system. To select the subpackets suitable for retransmission, a cyclic redundancy check (CRC) was employed at the subpacket level.

Coded caching with linear subpacketization is possible using Ruzsa-Szeméredi graphs [PDF]
2017 IEEE International Symposium on Information Theory (ISIT), 2017 Coded caching is a problem where encoded broadcasts are used to satisfy users requesting popular files and having caching capabilities. Recent work by Maddah-Ali and Niesen showed that it is possible to satisfy a scaling number of users with only a constant number of broadcast transmissions by exploiting coding and caching.

Device-to-Device Caching Networks with Subquadratic Subpacketizations
GLOBECOM 2017 - 2017 IEEE Global Communications Conference, 2017We consider wireless device-to-device (D2D) caching networks with single-hop transmissions. Previous work in the literature has shown that caching and coded multicasting can be strategically used to significantly increase the per user throughput. However, these schemes require partitioning files into a large number of packets which grows exponentially ...

Characteristics of Subpacket Structures in Ground EMIC Wave Observations
Journal of Geophysical Research: Space Physics, 2018AbstractRecent studies using satellite observations have reported that subpacket structures play an important role in determining the characteristics of electromagnetic ion cyclotron (EMIC) rising/falling tone emissions. The purpose of the present study is to investigate the subpacket structure characteristics in the ground observations of the EMIC ...
