What is research?
I think you know you've done
good research if only you have either
a) solved
one of other people's problems, or
b) convinced
other people to adopt one of your problems.
Research Topics
The
research activities are in the area of theory and design of wireless
communication networks.
In these slides I present a few results and
visions on some hot topics within interference-limited wireless networks
(based on a keynote speech, Sept. 2010).
PHYSICAL LAYER DESIGN
Original background is in signal processing techniques for wireless
communications, with recent emphasis on cross-layer issues:
- multi-user algorithms
- Cross-layer
design (including channel-aware user scheduling)
- Smart antenna algorithms and MIMO (see
“publications” for a couple of tutorial papers on the topic)
- Cooperative and distributed MIMO processing
- Distributed resource allocation and interference
mitigation (see “publications” for a recent tutorial paper on
the topic)
LINK LEVEL DESIGN
Over the last few years I have also worked in link
layer design, in particular
- Adaptive modulation and coding in broadband
(OFDM) wireless systems
- Scheduling algorithms with full and partial
channel state information
- Combined physical/link layer design for
performance optimization of TCP/IP over wireless.
SYSTEM LEVEL DESIGN
Finally I have interests in wireless network optimization and trade-off
analysis:
- Wireless access performance (capacity coverage ..)
- Cellular engineering, interference analysis and
control
- Impact of smart antenna systems, incl. MIMO
- Multiple access techniques
- Distributed multi-cell scheduling and resource
allocation
- Self-organizing wireless networks
- "Virtual" MIMO in ad-hoc networks
