Subpacketization in Coded Caching

Keywords:
Coded caching; Subpacketization

Description

In some communication systems end users are equiped with storages, the communication load during the peak hours can be reduced by having users pre-fetch part of the content during the scilent hours. Coded caching is a study to design the pre-fetching without the knowledge of users demands and the delivery scheme based on the users caches. However, many current schemes are facing the subpacketization problem in order to achieve the optimal load.

Prerequisites

Basic programming

Coded Placement in Coded Caching

Keywords:
Coded caching

Description

Coded caching is a study to reduce the transmission delay in broad-/multi-cast by designing the cached data and the transmitting data with coding strategies. There are two phases in coded cahing schemes, placement phase and delivery phase. Coding scheme can be applied in both phase in order to gain in reducing the transmission delay.

Prerequisites

Linear Algebra
Basic Programming
Channel Coding (Recommended)
