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…
Influence of Dataset Parameters on the Performance of Direct UE Positioning via Deep Learning
Baptiste Chatelier, Vincent Corlay, Cristina Ciochina +2
User equipment (UE) positioning accuracy is of paramount importance in current and future communications standard. However, traditional methods tend to perform poorly in non line o…
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…
