The
University of Hawaii (UH) has been one of the pioneers
in the area of wireless communications technology, having
developed, over thirty years ago, the first wireless packet
radio system based on ALOHA protocol. Ideas used in this
protocol strongly influenced the development of the CSM/CD
access protocol used in Ethernet, the network model most
widely used in computer communications. More recently,
and with the recruiting of new faculty, the research focus
at UH has been shifting more towards the physical-layer
type of projects including innovative antenna designs ;
DSP for smart antennas, blind-multiuser detection, and
cooperative diversity ; propagation prediction and modeling
of wireless networks ; RF and quasi-optical devices]; and
the development of computationally and power-efficient
iterative decoding algorithms for wireless communications
systems.
The Hawaii Center for Advanced Communications (HCAC) at
the University of Hawaii, Manoa Campus, is a research and
education center established in 2000 by the Board of Regents
in the College of Engineering. HCAC supports research and
training on a wide range of advanced communications technologies.
Special emphasis is on broadband wireless communications
and integrated communications systems that include wireless
optical, power- line, and satellite communications.
Research in progress at
the University of Hawaii’s
College of Engineering’s HCAC include: Advanced channel
modeling, computationally and power efficient iterative
decoding techniques, DSP with emphasis on multi-user detection,
multi-band antennas, high-performance/low-cost phase shifters,
phased array antennas with beam-steering capabilities,
and electronic high frequency packaging and interconnects.
