Abstract:
The latest mobile applications and the growing number of wireless users are
increasing the demand for high-throughput wireless access solutions.
Multiple-input multiple-output (MIMO) technology combined with orthogonal
frequency-division multiplexing (OFDM) constitute today's most promising
approach to exploit the limited radio frequency resources in a highly efficient
way. Unfortunately, the adoption of these technologies significantly increases
the signal processing complexity, what ultimately calls for dedicated
very-large scale integration (VLSI) circuits. At system-level, careful
evaluation of MIMO preprocessing aspects offers great opportunities for
lowering MIMO detection complexity. This work focuses on VLSI circuits for MIMO
preprocessing, with emphasis on QR decomposition-based architectures, and
contains considerations for joint algorithmic and architectural optimizations.
Several architectures have been realized as integrated circuits, including one
proving its full operational capabilities by being successfully deployed to a
real-time MIMO-OFDM testbed.
About the Author
Peter Jan Lüthi was born
in Schlieren, Switzerland, in 1977. He received his diploma degree in
electrical engineering from the ETH Zurich, Switzerland, in 2001. In the same
year, he joined Advanced Micro Devices (AMD) in order to work on HyperTransport
and PCI verification and performance enhancements. In late 2003, he started his
doctoral studies at the Integrated Systems Laboratory of the ETH Zurich,
working on digital signal processing and integrated circuit design for MIMO
wireless communication.
Keywords: MIMO preprocessing, V-BLAST, sorted QR
decomposition, MMSE, Givens rotations, CORDIC, VLSI, ASIC.
