Abstract:
In recent years, multiple-input
multiple-output (MIMO) communication techniques have established as main means
to put wireless communication to a new performance level. MIMO communication
employs multiple antennas at the transmitter and at the receiver and transmits
multiple data streams concurrently and within the same frequency band. However,
the benefits of MIMO technology come at the cost of significantly increased
computational complexity (compared to single antenna systems), especially in
the receiver.
This
dissertation presents the design of a modular hardware platform (i.e., testbed)
for testing and experimentation of MIMO communication aspects. Different MIMO
detection algorithms are realized on the testbed or as stand-alone VLSI
circuit. Algorithmic and architectural optimizations are presented that
eventually lead to more efficient solutions. Finally, measurements are carried
out on the testbed to verify our theoretical findings through our practical
implementations.
About the Author
Markus Wenk was born in 1980 in
Altstaetten, Switzerland. He received the MSc degree in electrical engineering from the Swiss
Federal Institute of Technology (ETH) Zurich, Switzerland, in 2005. Since 2006,
he has been a research assistant at the Integrated Systems Laboratory (IIS) of
ETH Zurich. His research interests include rapid prototyping and algorithms for
wireless communication and its realization in practical systems.
