One-Step Generative CSI Prediction
Mehdi Sattari, Javad Aliakbari, Alexandre Graell i Amat +1
Channel state information (CSI) prediction has emerged as a promising approach for mitigating channel aging in wireless communication systems. Recently, generative models have been…
Subgraph Federated Learning via Spectral Methods
Javad Aliakbari, Johan Östman, Ashkan Panahi +1
We consider the problem of federated learning (FL) with graph-structured data distributed across multiple clients. In particular, we address the prevalent scenario of interconnecte…
Bounds on Perfect Node Classification: A Convex Graph Clustering Perspective
Firooz Shahriari-Mehr, Javad Aliakbari, Alexandre Graell i Amat +1
We present an analysis of the transductive node classification problem, where the underlying graph consists of communities that agree with the node labels and node features. For no…
Algorithms for Joint Phase Estimation and Decoding for MIMO Systems in the Presence of Phase Noise
Rajet Krishnan, Giulio Colavolpe, Alexandre Graell i Amat +1
In this work, we derive the maximum a posteriori (MAP) symbol detector for a multiple-input multiple-output system in the presence of Wiener phase noise due to noisy local oscillat…
