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…
Placement Delivery Array for Cache-Aided MIMO Systems
Yifei Huang, Kai Wan, Minquan Cheng +2
We consider a cache-aided multiple-input multiple-output (MIMO) network, where a server equipped with antennas and a library of equal-size files communicates…
A New Construction Structure on MISO Coded Caching with Linear Subpacketization: Half-Sum Disjoint Packing
Bowen Zheng, Minquan Cheng, Kai Wan +1
In the cache-aided multiple-input single-output (MISO) broadcast channel (BC) system, the server is equipped with antennas and communicates with single-antenna…
Distributed Linearly Separable Computation with Arbitrary Heterogeneous Data Assignment
Ziting Zhang, Kai Wan, Minquan Cheng +2
Distributed linearly separable computation is a fundamental problem in large-scale distributed systems, requiring the computation of linearly separable functions over different dat…
Hybrid Iterative Detection for OTFS: Interplay between Local L-MMSE and Global Message Passing
Ruohai Yang, Shuangyang Li, Han Yu +3
Orthogonal time frequency space (OTFS) modulation has emerged as a robust solution for high-mobility wireless communications. However, conventional detection algorithms, such as li…
