Title
Design of radio front-end architectures to meet low energy consumption or resource sharing objectives

Abstract
The contributions presented are structured around four main research areas :
i) the energy consumption of connected devices, with the proposal of asynchronous wake-up radio solutions;
ii) the harvesting of ambient electromagnetic energy;
iii) the design of UHF RFID tags that are robust to elongation or integrate sensing capabilities (humidity/temperature), and on the other hand, studies on the tag-to-tag communication concept;
iv) the reduction of the dynamic range of input signals of analog-to-digital converters, as well as the joint implementation of spatial modulation and a full-duplex mode.
Depending on the addressed topic, the studies presented in this manuscript include theoretical, simulation, experimental, and real-world testing, with particular attention to the non-idealities of the radio front-end building
blocks and their impact on performance.
Based on the acquired expertise and the collaborations conducted at the national and international levels in various contexts, the final section identifies several new research directions that are being considered.

Title
From Bayesian Statistics to Large-Scale MIMO Communications

Abstract
Large-scale MIMO systems have emerged as a cornerstone for next-generation wireless communication networks. While extended research has been conducted on signal processing and transceiver design in these systems, the fundamental Shannon capacity limit remains elusive in many settings, particularly in the presence of system non-linearities. In this talk, we explore the connection between statistics and communication, and introduce a novel approach that leverages information-theoretic asymptotics from Bayesian statistics to derive the Shannon capacity of such systems. We reveal the critical role of the Fisher information and Jeffreys’ prior in this characterization, and
demonstrate how to apply this method to derive the asymptotic capacity of various channel models. Examples include the MIMO channels with 1-bit ADC, clipping, phase noise, and imperfect channel state information.

Biography
Sheng Yang received the B.E. degree in electrical engineering from Jiaotong University, Shanghai, China, in 2001, and both the engineer degree and the M.Sc. degree in electrical engineering from Telecom ParisTech, Paris, France, in 2004, respectively. In 2007, he obtained his Ph.D. from Université de Pierre et Marie Curie (Paris VI).
From October 2007 to November 2008, he was with Motorola Research Center in Gif-sur-Yvette, France, as a senior staff research engineer.
Since December 2008, he has joined CentraleSupélec, Paris-Saclay University, where he is currently a full professor. From April 2015, he also holds an honorary associate professorship in the department of electrical and electronic engineering of the University of Hong Kong (HKU).
He received the 2015 IEEE ComSoc Young Researcher Award for the Europe, Middle East, and Africa Region (EMEA). He was an associate editor of the IEEE transactions on wireless communications from 2015 to 2020.
He is currently an associate editor of the IEEE transactions on information theory.
