On Demand-Private Coded Caching With Multiple Demands
Qinyi Lu, Nan Liu, Wei Kang
We consider a coded caching problem with multiple demands under a privacy constraint. In this problem, a server with access to \(N\) files serves \(K\) users over a shared link, an…
Sum Rate optimization for RIS-Aided RSMA system with Movable Antenna
Mingyu Hu, Nan Liu, Wei Kang
Rate-Splitting Multiple Access (RSMA) is a key enabling technique for sixth-generation (6G) wireless systems due to its powerful interference management, and Reconfigurable Intelli…
Movable Antenna Assisted Dual-Polarized Multi-Cell Cooperative AirComp: An Alternating Optimization Approach
Mingyu Hu, Nan Liu, Wei Kang
Over-the-air computation (AirComp) is a key enabler for distributed optimization, since it leverages analog waveform superposition to perform aggregation and thereby mitigates the…
Characterizing the Optimal Memory-Rate Tradeoff in Secure Coded Caching for Small Buffer or Small Rate
Han Fang, Nan Liu, Wei Kang
We consider the secure coded caching problem proposed by Ravindrakumar et. al where no user can obtain information about files other than the one requested. We first propose three…
Demand Private Coded Caching: Small Cache Size
Qinyi Lu, Nan Liu, Wei Kang +1
We investigate the demand private coded caching problem, which is an coded caching problem with files, users, each equipped with a cache of size , and an additio…
Capacity of Hierarchical Secure Coded Gradient Aggregation with Straggling Communication Links
Qinyi Lu, Jiale Cheng, Wei Kang +1
The growing privacy concerns in distributed learning have led to the widespread adoption of secure aggregation techniques in distributed machine learning systems, such as federated…
