Scalable Distortion-Aware Clustering for Fronthaul-Limited Cell-Free MIMO Networks
Zehua Li, Raviraj Adve, Israfil Bahceci +1
This paper studies distortion-aware clustering for uplink fronthaul-limited cell-free MIMO networks employing maximum ratio combining (MRC). While MRC is appealing for its low-comp…
Robust Segmented Analog Broadcast Design to Accelerate Wireless Federated Learning
Chong Zhang, Ben Liang, Min Dong +2
We consider downlink broadcast design for federated learning (FL) in a wireless network with imperfect channel state information (CSI). Aiming to reduce transmission latency, we pr…
Matrix Pencil-Based DoA Estimation for Hybrid Receivers in Snapshot-Limited Scenarios
Mona Mostafa, Ramy H. Gohary, Amr El-Keyi +1
The goal of this paper is to estimate the directions of arrival (DoAs) for hybrid analog/digital (HAD) receivers when the number of snapshots is too small for statistical averaging…
SegOTA: Accelerating Over-the-Air Federated Learning with Segmented Transmission
