Distributed Beam Alignment in sub-THz D2D Networks
Fernando Pedraza, Jan Christian Hauffen, Fabian Jaensch +2
Devices in a device-to-device (D2D) network operating in sub-THz frequencies require knowledge of the spatial channel that connects them to their peers. Acquiring such high dimensi…
Compressed Sensing Inspired User Acquisition for Downlink Integrated Sensing and Communication Transmissions
Yi Song, Fernando Pedraza, Shuangyang Li +3
This paper investigates radar-assisted user acquisition for downlink multi-user multiple-input multiple-output (MIMO) transmission using Orthogonal Frequency Division Multiplexing…
Extended Target Parameter Estimation and Tracking with an HDA Setup for ISAC Applications
Fernando Pedraza, Saeid K. Dehkordi, Jan C. Hauffen +3
We investigate radar parameter estimation and beam tracking with a hybrid digital-analog (HDA) architecture in a multi-block measurement framework using an extended target model. I…
Simultaneous Communication and Tracking in Arbitrary Trajectories via Beam-Space Processing
Fernando Pedraza, Saeid K. Dehkordi, Mari Kobayashi +1
In this paper, we develop a beam tracking scheme for an orthogonal frequency division multiplexing (OFDM) Integrated Sensing and Communication (ISAC) system with a hybrid digital a…
Beam Refinement and User State Acquisition via Integrated Sensing and Communication with OFDM
Fernando Pedraza, Mari Kobayashi, Giuseppe Caire
The performance of millimeter wave (mmWave) communications strongly relies on accurate beamforming both at base station and user terminal sides, referred to as beam alignment (BA).…
