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…
Achievable Rates for a Distributed Antenna System with No Channel State Information at the Central Processor
Yi Song, Hao Xu, Kai Wan +3
A recent trend in wireless communications considers the migration of traditional monolithic base stations to the so-called disaggregated architecture, where radio units (RUs) imple…
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…
Multi-Message Secure Aggregation with Demand Privacy
Chenyi Sun, Ziting Zhang, Kai Wan +1
This paper considers a multi-message secure aggregation with privacy problem, in which a server aims to compute linear combinations of local inputs from dis…
Frequency-Space Channel Estimation and Spatial Equalization in Wideband Fluid Antenna System
Xuehui Dong, Kai Wan, Shuangyang Li +2
The Fluid Antenna System (FAS) overcomes the spatial degree-of-freedom limitations of conventional static antenna arrays in wireless communications.This capability critically depen…
Hierarchical Gradient Coding: From Optimal Design to Privacy at Intermediate Nodes
Ali Gholami, Tayyebeh Jahani-Nezhad, Kai Wan +1
Gradient coding is a distributed computing technique for computing gradient vectors over large datasets by outsourcing partial computations to multiple workers, typically connected…
