Improved Multi-access Coded Caching Schemes from Cross Resolvable Designs

TL;DR

This paper generalizes existing multi-access coded caching schemes based on Cross Resolvable Designs, leading to improved rate-per-user performance in caching networks.

Contribution

It introduces a generalized framework for multi-access coded caching schemes that enhances rate-per-user using resolvable design principles.

Findings

Achieved improved rate-per-user in caching schemes.

Extended the class of resolvable designs applicable to caching.

Demonstrated theoretical performance gains over previous schemes.

Abstract

Recently multi-access coded caching schemes with number of users different from the number of caches obtained from a special case of resolvable designs called Cross Resolvable Designs (CRDs) have been reported and a new performance metric called rate-per-user has been introduced \cite{KNRarXiv}. In this paper we present a generalization of this work resulting in multi-access coded caching schemes with improved rate-per-user.
