Job description

In indoor environments such as homes and
offices, wireless communication technology is spreading rapidly. To
enable increased throughput, this technology will increasingly exploit
multiple antennas at both the transmitting and receiving ends of the
communication system. This approach is often referred to as MIMO
(Multi-Input Multi-Output). The first WLAN (wireles local-area network)
products using MIMO technology have recently entered the market. As yet
these products are relatively costly and power-hungry, and have limited
resistance to (ever increasing) interference. For MIMO technology to
attain mass-market appeal, these drawbacks need to be overcome. The
present project aims to make an important step in this direction by
joint optimization of the radio-frequency (RF) and baseband (BB) parts
of the transceiver. These parts are normally designed largely
independently, and a joint optimization is expected to enable
substantially lower power dissipation, lower cost, and higher
resilience to interference. Possible approaches include:
Novel transceiver topologies, with e.g. fewer RF front-ends than
antennas, and a redefinition of the RF/BB borderline.
Dealing with RF imperfactions in the BB part of the transceiver, rather
than preventing them at RF. This approach is sometimes called `dirty
c) Inclusion in the RF part of calibrations (of e.g.
components or bias currents), based on information extracted at
baseband. In this way the RF front-end can accept considerably higher
intrinsic tolerances, potentially resulting in significant reductions
of complexity/cost and power Dissipation.
d) Dynamic adaptation of
the RF part of the transceiver in response to conditions of the
communication channel as estimated at baseband. This would, for
example, require a high power dissipation only during the small
fraction of the time when reception conditions are poorest.
of these possibilities requires a collaborative effort between experts
in RF transceiver technology and in baseband signal-processing. For
this reason the project involves two Ph.D. positions, one focusing on
RF technology and embedded in the mixed-signal microelectronics (MSM)
group at TU/e, and the other one focusing on baseband signal
processing, embedded in the signal processing systems (SPS) group. The
project is based partly at TU/e and partly at the Connectivity
Solutions group at Philips Research Laboratories. It involves experts
from TU/e and Philips and forms part of a broader effort, together with
the Universities of Delft and Twente, towards a demonstrator of a
`mass-market’ MIMO system. This demonstrator should incorporate some of
the approaches developed within the project.


Candidates for these positions
should have a Master’s degree in Electrical Engineering or Physics with
excellent grades (first class honors or equivalent). For the position
in the MSM group a specialization in mixed-signal electronics and
circuit design is required, along with a demonstrable interest in
signal processing. For the position in the SPS group, a strong basis in
mathematics, signal processing, information theory or control systems
is required, along with a serious interest in circuit design, and an
ability to capture the essential behaviour of circuits in simple
mathematical signal-processing models. For both positions, other key
attributes include good analytic, synthetic, experimental and
(object-oriented) programming skills, excellent social and team working
skills, and an ability to turn chaos into order.

Technische Universiteit Eindhoven Department of Electrical Engineering

The Department of Electrical Engineering
concerns the research and education of the Electrical Engineering
discipline. Electrical Engineering covers the application of electrical
phenomena with respect to energy transfer, telecommunication, and
calculation and processing of information and the technology involved.
Both hardware, in the form of electronic circuits and accessories, and
software, in the form of system software for electro-technical
application, are the subject of study. Existing and new electrical
components and systems are analyzed, designed and realized. In
addition, the maintenance of these systems is the subject of research,
as is the relevance for society of electrical engineering and
