A Low-Complexity Framework for Multi-access Coded Caching Systems with Arbitrary User-cache Access Topology
Ting Yang, Kai Wan, Minquan Cheng +3
This paper studies the multi-access coded caching (MACC) problem with arbitrary user-cache access topology, which extends existing MACC models that rely on highly structured and co…
A New Construction Structure on Multi-access Coded Caching with Linear Subpacketization: Cyclic Multi-Access Non-Half-Sum Disjoint Packing
Mengyuan Li, Minquan Cheng, Kai Wan +1
We consider the multi-access coded caching system introduced by Hachem et al., which consists of a central server with files and cache nodes, each of memory siz…
On the Optimality of Coded Distributed Computing for Ring Networks
Zhenhao Huang, Minquan Cheng, Kai Wan +2
We consider a coded distributed computing problem in a ring-based communication network, where computing nodes are arranged in a ring topology and each node can only communicat…
Entropy Functions on Two-Dimensional Faces of Polymatroidal Region of Degree Four: Part II: Information Theoretic Constraints Breed New Combinatorial Structures
Shaocheng Liu, Qi Chen, Minquan Cheng
Characterization of entropy functions is of fundamental importance in information theory. By imposing constraints on their Shannon outer bound, i.e., the polymatroidal region, one…
Proactive Coded Caching Scheme for D2D Networks
Qiaoling Zhang, Changlu Lin, Minquan Cheng
Coded caching and device-to-device (D2D) communication are two effective techniques for alleviating network traffic. Secure transmission and file privacy have also become critical…
A Construction Framework of Coded Caching Scheme for Multi-Access MISO Systems via Knapsack Problem
Siying Luo, Youlong Wu, Mingming Zhang +2
This paper investigates the coded caching problem in a multi-access multiple-input single-output (MAMISO) network with the combinatorial topology. The considered system consists of…
