Noncoherent ISAC over Block-Fading Channels: Asymptotic Performance Analysis
Hao Yang, Kai Wan, Giuseppe Caire
This paper investigates the fundamental limits and optimal signal distribution design for Integrated Sensing and Communication (ISAC) systems operating under strictly noncoherent c…
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…
Multiaccess Coded Caching with Heterogeneous Retrieval Costs
Wenbo Huang, Minquan Cheng, Kai Wan +3
The multiaccess coded caching (MACC) system, as formulated by Hachem {\it et al.}, consists of a central server with a library of files, connected to cache-less users via a…
A New Construction Structure on Coded Caching with Linear Subpacketization: Non-Half-Sum Latin Rectangle
Yongcheng Yang, Minquan Cheng, Kai Wan +1
Coded caching is recognized as an effective method for alleviating network congestion during peak periods by leveraging local caching and coded multicasting gains. The key challeng…
