Placement Delivery Array Based on Concatenating Construction
IEEE Communications Letters, 2020In the coded caching problem apart from transmission rate, reducing the number of packets $F$ ia also meaningful for practical implementation for coded caching scheme. Yan et al. reformulate the centralized coded caching schemes as designing a corresponding placement delivery array (PDA).

Placement Delivery Array and Its Applications
2018 IEEE Information Theory Workshop (ITW), 2018Recently, placement delivery array (PDA) was formulated to describe the placement and delivery phases with a single array for centralized coded caching scheme in an error-free shared link. In this paper, we explore PDA characterizations for two other models: device-to-device (D2D) network and distributed computing system.

An Approach to Reduce the Redundancy of Placement Delivery Array Schemes for Random Demands
IEEE Wireless Communications Letters, 2021Centralized coded caching schemes have been widely studied in wireless networks. Placement delivery array (PDA) can be used to generate a coded caching scheme with low subpacketization when all the requested files are different. However, all existing schemes based on PDA design treat the request of each user as an independent file, without leveraging ...

Coded MapReduce Schemes Based on Placement Delivery Array
2019 IEEE International Symposium on Information Theory (ISIT), 2019The coded MapReduce framework introduced in [1] gives a method to tradeoff extra computation for reduced communication, in-order to speedup operations for which communication is the bottleneck. In [2], it has been demonstrated that reducing the number of subfiles required in coded MapReduce at the cost of a slightly higher communication load is ...

Optimizing MIMO Antenna Placement and Array Configurations for Multimedia Delivery in Aircraft
IEEE Vehicular Technology Conference, 2007In this paper, the feasibility of multiple-input multiple-output (MIMO) systems in aircraft is examined for the specific application of seatback entertainment, using an approach built around a site-specific capacity analysis methodology. The average capacity is evaluated as a function of the seat location, using the proposed methodology that relies on ...
