Palaiseau (France), 2024-02-27

Email : dpham@telecom-paris.fr

Phone : +33 1 23 45 67 89

Duration : 3 months

Degree : Excellent students in their final Year of Bachelor or 1st Year of Master

Fields : (Computer Science, Electrical Engineering) Signal processing, Power Amplifier modeling

Start date : 2024-07-01

Introduction

In wireless communication systems, power amplifiers (PAs) are essential for amplifying low-power radio frequency (RF) signals to higher power levels for transmission. As the demand for higher data rates grows, and with the use of complex modulation schemes, the efficiency and performance of PAs become critical.

PA modeling is a fundamental tool for design and improvement of wireless communication systems. It is used for mimicking the behavior of power amplifiers under different operating conditions whithout performing actual hardware experiments.

The standard approach consists of performing actual measurements on the hardware device to be modeled. A (discrete-time) model, whose operating sampling rate is related to the available generation and acquisition hardware, is then extracted. Those measurements can be time-consuming and expensive.

Project description

This project aims to develop a multi-rate PA model that can handle different sampling rates. This will allows to use the same model for different hardware configurations and to perform quick simulations.

Hosting laboratory

Laboratoire Traitement et Communication de l’Information (LTCI)

Research team

The Circuits et Systèmes de Communication (C2S) team is internationally recognized for its ability to integrate digital intelligence into AMS and RF SoCs such as analog-to-digital converters (ADCs) or RF receivers for cognitive radio. By combining its expertise in the physical realization of the CMOS chip with its experience in signal processing and its knowledge of the other network layers for which LTCI’s skills are recognized, the group designs high-performance AMS and RF SoCs. The aim is to develop elements or "building blocks", enabling the system of connected objects to be interfaced on one side with the physical world via sensors, and on the other side with the system core via communications, in particular RF.
