Enabling Energy-Efficiency in Massive-MIMO: A Scalable Low-Complexity Decoder for Generalized Quadrature Spatial Modulation
Hyeon Seok Rou, Giuseppe Thadeu Freitas de Abreu, David González G. +1
Generalized quadrature spatial modulation (GQSM) schemes are known to achieve high energy- and spectral- efficiencies by modulating information both in transmitted symbols and in c…
Soft-connected Rigid Body Localization: State-of-the-Art and Research Directions for 6G
Niclas Führling, Hyeon Seok Rou, Giuseppe Thadeu Freitas de Abreu +2
This white paper describes a proposed article that will aim to provide a thorough study of the evolution of the typical paradigm of wireless localization (WL), which is based on a…
Sparse Codesigned Communication and Radar Systems
Hyeon Seok Rou, Giuseppe Thadeu Freitas de Abreu, Saravanan Nagesh +4
In the envisioned beyond-fifth-generation (B5G) and sixth-generation (6G) scenarios which expect massive multiple-input multiple-output (mMIMO) and high frequency communications in…
AFDM vs OTFS: A Comparative Study of Promising Waveforms for ISAC in Doubly-Dispersive Channels
Hyeon Seok Rou, Giuseppe Thadeu Freitas de Abreu, Junil Choi +4
**PLEASE FIND THE FULL EXTENDED ARTICLE "From OTFS to AFDM: A Comparative Study of Next-Generation Waveforms for ISAC in Doubly-Dispersive Channels" (Accepted for publication at th…
Integrated Sensing and Communications for 3D Object Imaging via Bilinear Inference
Hyeon Seok Rou, Giuseppe Thadeu Freitas de Abreu, David González G. +1
We consider an uplink integrated sensing and communications (ISAC) scenario where the detection of data symbols from multiple user equipment (UEs) occurs simultaneously with a thre…
A New Noncoherent Gaussian Signaling Scheme for Low Probability of Detection Communications
Yuma Katsuki, Giuseppe Thadeu Freitas de Abreu, Koji Ishibashi +1
We propose a novel, Gaussian signaling mechanism for low probability of detection (LPD) communication systems with either single or multiple antennas. The new scheme is designed to…
