Minimum Energy per Bit of Unsourced Multiple Access with Location-Based Codebook Partitioning

Deekshith Pathayappilly Krishnan, Kaan Okumus, Khac-Hoang Ngo +1

We derive finite-blocklength bounds on the minimum achievable energy per bit over a Gaussian unsourced multiple access (UMA) channel in the presence of heterogeneous path-loss cond…

Type-Based Unsourced Multiple Access Over Fading Channels in Distributed MIMO With Application to Multi-Target Localization

Kaan Okumus, Khac-Hoang Ngo, Giuseppe Durisi +1

We consider the problem of type estimation over unsourced multiple access fading channels in distributed multiple-input multiple-output (D-MIMO) systems. Unlike classical unsourced…

Type-Based Unsourced Federated Learning With Client Self-Selection

Kaan Okumus, Khac-Hoang Ngo, Unnikrishnan Kunnath Ganesan +3

We address the client-selection problem in federated learning over wireless networks under data heterogeneity. Existing client-selection methods often rely on server-side knowledge…

MATTER: Multiscale Attention for Registration Error Regression

Shipeng Liu, Ziliang Xiong, Khac-Hoang Ngo +1

Point cloud registration (PCR) is crucial for many downstream tasks, such as simultaneous localization and mapping (SLAM) and object tracking. This makes detecting and quantifying…

Distributed MIMO With Over-the-Air Phase Calibration Integrated Into the TDD Flow

Khac-Hoang Ngo, Erik G. Larsson

Reciprocity-based, joint coherent downlink beamforming from multiple access points (APs) in distributed multiple-input multiple-output (MIMO) with independent local oscillators (LO…

Noncoherent MIMO Communications: Theoretical Foundation, Design Approaches, and Future Challenges

Khac-Hoang Ngo, Diego Cuevas, Ruben de Miguel Gil +3

Noncoherent communication is a promising paradigm for future wireless systems where acquiring accurate channel state information (CSI) is challenging or infeasible. It provides met…
