Deep Unfolding-Empowered MmWave Massive MIMO Joint Communications and Sensing
Nhan Thanh Nguyen, Ly V. Nguyen, Nir Shlezinger +3
In this paper, we propose a low-complexity and fast hybrid beamforming design for joint communications and sensing (JCAS) based on deep unfolding. We first derive closed-form expre…
Non-Reciprocal Reconfigurable Intelligent Surfaces
Jiaqi Xu, Haoyu Wang, Rang Liu +2
In contrast to conventional RIS, the scattering matrix of a non-reciprocal RIS (NR-RIS) is non-symmetric, leading to differences in the uplink and the downlink components of NR-RIS…
Performance Analysis and Power Allocation for Massive MIMO ISAC Systems
Nhan Thanh Nguyen, Van-Dinh Nguyen, Hieu V. Nguyen +3
Integrated sensing and communications (ISAC) is envisioned as a key feature in future wireless communications networks. Its integration with massive multiple-input-multiple-output…
CRB Optimization using a Parametric Scattering Model for Extended Targets in ISAC Systems
Rang Liu, A. Lee Swindlehurst, Ming Li
This paper presents a novel parametric scattering model (PSM) for sensing extended targets in integrated sensing and communication (ISAC) systems. The PSM addresses the limitations…
Channel-Coded Precoding for Multi-User MISO Systems
Ly V. Nguyen, Junil Choi, Bjorn Ottersten +1
Precoding is a critical and long-standing technique in multi-user communication systems. However, the majority of existing precoding methods do not consider channel coding in their…
