Sampling-Free Diffusion Transformers for Low-Complexity MIMO Channel Estimation
Zhixiong Chen, Hyundong Shin, Arumugam Nallanathan
Diffusion model-based channel estimators have shown impressive performance but suffer from high computational complexity because they rely on iterative reverse sampling. This paper…
Large Language Model-Empowered Channel Prediction and Predictive Beamforming for LEO Satellite Communications
Zhixiong Chen, Hyundong Shin, Arumugam Nallanathan +1
Accurate channel prediction and effective beamforming are essential for low Earth orbit (LEO) satellite communications to enhance system capacity and enable high-speed connectivity…
Knowledge-aided Federated Learning for Energy-limited Wireless Networks
Zhixiong Chen, Wenqiang Yi, Yuanwei Liu +1
The conventional model aggregation-based federated learning (FL) approach requires all local models to have the same architecture, which fails to support practical scenarios with h…
Dynamic Task Software Caching-assisted Computation Offloading for Multi-Access Edge Computing
Zhixiong Chen, Wenqiang Yi, Atm S. Alam +1
In multi-access edge computing (MEC), most existing task software caching works focus on statically caching data at the network edge, which may hardly preserve high reusability due…
