Beam-Space MIMO Radar for Joint Communication and Sensing with OTFS Modulation

no code implementations12 Jul 2022 Saeid K. Dehkordi, Lorenzo Gaudio, Mari Kobayashi, Giuseppe Caire, Giulio Colavolpe

Under this setup, we propose a likelihood function-based scheme to perform joint target detection and parameter estimation in Discovery, and high-resolution parameter estimation in Tracking mode, respectively.

Simultaneous Communication and Tracking in Arbitrary Trajectories via Beam-Space Processing

no code implementations29 Mar 2022 Fernando Pedraza, Saeid K. Dehkordi, Mari Kobayashi, Giuseppe Caire

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 analog (HDA) architecture operating in the millimeter wave (mmWave) band.

Scalable Vector Gaussian Information Bottleneck

no code implementations15 Feb 2021 Mohammad Mahdi Mahvari, Mari Kobayashi, Abdellatif Zaidi

In the context of statistical learning, the Information Bottleneck method seeks a right balance between accuracy and generalization capability through a suitable tradeoff between compression complexity, measured by minimum description length, and distortion evaluated under logarithmic loss measure.

Variational Inference

D2D-Aided Multi-Antenna Multicasting under Generalized CSIT

no code implementations2 Feb 2021 Placido Mursia, Italo Atzeni, Mari Kobayashi, David Gesbert

Multicasting, where a base station (BS) wishes to convey the same message to several user equipments (UEs), represents a common yet highly challenging wireless scenario.

On the Relevance-Complexity Region of Scalable Information Bottleneck

no code implementations2 Nov 2020 Mohammad Mahdi Mahvari, Mari Kobayashi, Abdellatif Zaidi

The Information Bottleneck method is a learning technique that seeks a right balance between accuracy and generalization capability through a suitable tradeoff between compression complexity, measured by minimum description length, and distortion evaluated under logarithmic loss measure.

Hybrid Digital-Analog Beamforming and MIMO Radar with OTFS Modulation

no code implementations17 Sep 2020 Lorenzo Gaudio, Mari Kobayashi, Giuseppe Caire, Giulio Colavolpe

The second scenario considers narrow angular beams to send information streams individually to the already detected users and simultaneously keep tracking of their respective parameters.
