Multi-Model Wireless Federated Learning with Downlink Beamforming

ICASSP 2024accepted

This paper studies the design of wireless federated learning (FL) for simultaneously training multiple machine learning models. We consider round robin device-model assignment and downlink beamforming for concurrent multiple model updates. After formulating the joint downlink-uplink transmission pro…

Downlink Covariance Estimation in URA FDD Massive MIMO Systems

ICASSP 2023accepted

We propose a low-complexity downlink channel covariance matrix estimation for massive multiple-input multiple-output systems in which the base station (BS) is equipped with a uniform rectangular antenna array (URA). This scheme can be expressed in the form of an affine transformation which depends o…
