Fusion of Time and Angle Measurements for Digital-Twin-Aided Probabilistic 3D Positioning
Vincent Corlay, Viet-Hoa Nguyen, Nicolas Gresset
Previous studies explained how the 2D positioning problem in indoor non line-of-sight environments can be addressed using ray tracing with noisy angle of arrival (AoA) measurements…
Optimal Sensing Policy With Interference-Model Uncertainty
Vincent Corlay, Jean-Christophe Sibel, Nicolas Gresset
This paper considers a half-duplex scenario where an interferer behaves according to a parametric model but the values of the model parameters are unknown. We explore the necessary…
Probabilistic Positioning Via Ray Tracing With Noisy Angle of Arrival Measurements
Vincent Corlay, Viet-Hoa Nguyen, Nicolas Gresset
We consider the positioning problem in non line-of-sight (NLoS) situations, where several base stations (BS) try to locate a user equipment (UE) based on uplink angle of arrival (A…
Probabilistic Ray-Tracing Aided Positioning at mmWave frequencies
Viet-Hoa Nguyen, Vincent Corlay, Nicolas Gresset +1
We consider the following positioning problem where several base stations (BS) try to locate a user equipment (UE): The UE sends a positioning signal to several BS. Each BS perform…
Optimized pilot distribution to track the phase noise in DFT-s-OFDM for sub-THz systems
J. -C. Sibel, V. Corlay, A. Bechihi
In this paper, we focus on the selection of a pilot pattern to track the phase noise in high frequency bands in a DFT-s-OFDM chain. By considering the Wiener filter at the receiver…
An MDP approach for radio resource allocation in urban Future Railway Mobile Communication System (FRMCS) scenarios
Vincent Corlay, Jean-Christophe Sibel
In the context of railway systems, the application performance can be very critical and the radio conditions not advantageous. Hence, the communication problem parameters include b…
Minimizing the Outage Probability in a Markov Decision Process
Vincent Corlay, Jean-Christophe Sibel
Standard Markov decision process (MDP) and reinforcement learning algorithms optimize the policy with respect to the expected gain. We propose an algorithm which enables to optimiz…
A modified probabilistic amplitude shaping scheme to use sign-bit-like shaping with a BICM
Vincent Corlay, Hamidou Dembele
On the one hand, sign-bit shaping is a popular shaping scheme where the conditional probability of the sign bit is made non-equiprobable. On the other hand, probabilistic amplitude…
An application-oriented scheduler
Jean-Christophe Sibel, Nicolas Gresset, Vincent Corlay
We consider a multi-agent system where agents compete for the access to the radio resource. By combining some application-level parameters, such as the resilience, with a knowledge…
