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…
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…
