Professor, Simon Fraser University
Chair, Sierra Wireless
Research Statement:
From electronic and communication product design, I found that innovation requires not only signal processing, but also an understanding of the underlying physical mechanisms which are driving the need for signal processing solutions. This combination has become a theme of my research.
Research Interest:
Signal Processing Theory
Antenna Theory and Design
Wave Propagation Measurement and Modeling
Ongoing and Unlimited Topics:
Compact mammalian bio-implantable antennas,
Multiple element antenna (MEA) designs and evaluations,
Circularly polarized antennas,
Multifaceted structures for large arrays,
MIMO capacity optimization,
Blind and pre-coding techniques for OFDM,
Blind channel estimation
Physics-based algorithms for location estimation
Mobile antennas, including mutual coupling and distributed gain
Polarization diversity and downtilt for base stations
Signal processing algorithms for multiport receivers
Signal conversion stage signal processing
Beam space diversity: spacing for directive antennas and angular spacing
