A Decomposed Learning Framework for Hybrid Precoding

Learning-based hybrid precoding has emerged as a promising solution for low-latency multi-user transmission in large-scale antenna systems. However, its practical deployment is often hindered by high training overhead, and poor generalization across varying system sizes. These limitations fundamentally stem from the fa...

Cross-System Neural Precoder: Exploiting Structural Consistency for Fast Adaptation

Simulation results show that pre-trained XNPs achieve fast adaptation to new configurations with significantly fewer training samples and epochs than a graph neural network-based baseline, demonstrating that cross-system adaptability can be achieved by exploiting shared computational structure, rather than relying on l...

Positional Attention-based Graph Neural Network for Learning Permutation Non-equivariant Wireless Policies

This paper proposes a novel positional attention-based GNN to learn permutation nonequivariant policies efficiently, and employs the proposed GNN to learn the policies, where the embedding function is designed based on the channel covariance matrix.
