Power combining (Combi3D)
This project (THALES ALENIA SPACE / /CNES
contract 1 ) applies practical techniques and
architectures specific to the designing of high
combining output power amplifier in millimetric
band. As a result of the doctoral thesis financed
by the CNES in collaboration with Thalès Alenia
Space (TAS: K band), TAS applied for a patent. The
work continued with a 4-month Ka band study
(simulation) financed by TAS. Finally, a new oneyear
collaboration began at the end of 2008,
studying an X/Ku band combiner (financed by the
CNES). Additionally, the doctoral thesis financed
by the Institut Carnot (Ka band) is continuing and
a paper was proposed at the JNM2009.
MIMO
MIMO systems make it possible to provide an
increase in flow, while preserving the engaged
bandwidth, and thus to increase spectral
efficiency. These platforms must validate the
concepts implemented, and allow for the
emergence of new wave forms and standards.
1. Palmyre II (submitted under CPER 2007-2013)
This project began in December of 2008. It focuses
on developing a higher-order MIMO prototype.
Increasing frequency toward the millimetric range
1) CNES : Centre National d'Etudes Spatiales (National Centre for Space Studies)
is also part of the proposition, partly for material
investments, but also for the specific
investigations into modeling the propagation
channel.
2. REI (Recherche Etude Innovation 'Research
Study Innovation')
In collaboration with the company COMSIS and
WOLT (contact was made during Palmyre I), this
DGA project aims to "develop a multimedia
service demonstrator for wireless networks,
implementing MIMO technology". The goal is to
demonstrate the benefits of a MIMO transmission
in an operational framework, with detailed
specifications.
Radio over Fiber (RoF)
Given the evolution of technology, this project
aims to propose a type of radio deployment
engineering that breaks with traditional systems.
This new type of engineering will also have goals
related to health and consumption of electricity,
but will mainly make it possible to define an
appropriate technical response involving antenna
deployment for a fine-tuned optimization of radio
coverage.
1. OptiBus
The goal of this project, which is overseen by the
Image and Networks Center, is the development
of a prototype/platform for fiber-optic radio
deployment ; Telecom Bretagne is in charge of the
engineering part of the project, therefore the
engineering of the radio-optical interfaces (under
a 6-month temporary work contract). A Masterslevel
internship (2008) made it possible to predict
and determine the performances of the optical
and radio interfaces (theoretical and experimental
studies). Micromodule and the ENIB (National
Engineering School of Brittany) supervised a
Masters internship in parallel for the
implementation of the optics side of the project.
A first version (high-speed optical network) was
installed in early 2008, and a second one is slated
for 2009.
2. DataShade (preparation of Capil_R)
Datashade is a bibliographic synthesis associated
with a technical expertise on radio and antenna
