Architecture, Protocols, and Algorithms for Location-Aware Services in Beyond 5G Networks
Peter Hammarberg, Julia Vinogradova, Gábor Fodor +3
The automotive and railway industries are rapidly transforming with a strong drive towards automation and digitalization, with the goal of increased convenience, safety, efficiency…
EVM Mitigation with PAPR and ACLR Constraints in Large-Scale MIMO-OFDM Using TOP-ADMM
Shashi Kant, Mats Bengtsson, Gabor Fodor +2
Although signal distortion-based peak-to-average power ratio (PAPR) reduction is a feasible candidate for orthogonal frequency division multiplexing (OFDM) to meet standard/regulat…
IRS Phase-Shift Feedback Overhead-Aware Model Based on Rank-One Tensor Approximation
Bruno Sokal, Paulo R. B. Gomes, André L. F. de Almeida +2
In this paper, we propose a rank-one tensor modeling approach that yields a compact representation of the optimum IRS phase-shift vector for reducing the feedback overhead. The mai…
Semi-Blind Joint Channel and Symbol Estimation for IRS-Assisted MIMO Systems
Gilderlan Tavares de Araújo, André Lima Férrer de Almeida, Rémy Boyer +1
Intelligent reflecting surface (IRS) is a promising technology for the 6th generation of wireless systems, realizing the smart radio environment concept. In this paper, we present…
Optimizing Pilot Spacing in MU-MIMO Systems Operating Over Aging Channels
Sebastian Fodor, Gábor Fodor, Doğa Gürgünoğlu +1
In the uplink of multiuser multiple input multiple output (MU-MIMO) systems operating over aging channels, pilot spacing is crucial for acquiring channel state information and achi…
Vehicular Positioning and Tracking in Multipath Non-Line-of-Sight Channels
Zhicheng Ye, Julia Vinogradova, Gábor Fodor +1
We consider the downlink transmission in a single cell multiple-input multiple-output system, in which the user equipment correspond to a vehicle moving along a given trajectory. T…
