Research
The faculty of the Department of Electrical Engineering and Computer Science conduct research in various areas, including computer architecture, computer networking, wireless
communication, control theory, digital signal processing, distance learning, electromagnetics,
optics, power systems, and power quality.
Research in the computer architecture area involves design and implementation of efficient
block replacement algorithms for CPU cache and Disk cache. The computing facilities in the
CARG lab are used to conduct this research.
Research in computer networking involves comparison of networks that use voice over IP
and Voice over Frame-Relay. The impact of fragmentation and interleaving is also explored.
Challenges associated with Voice over IP over wireless methods are also being investigated.
Research in information security includes security issues in ad-hoc sensor networks, digital
forensics analysis, and biometric security (iris, finger print, and face recognition methods).
Research in image processing and video communications includes wavelet-based video
processing and compression, joint source-channel coding, visual sensor networks, video
surveillance, and information theoretic aspects of video communications.
Research in the area of digital communications systems includes smart antenna, the third
generation (3G) and fourth generation (4G) code division multiple access (CDMA) wireless
communications systems, and US-Army future frequency-hopping (FH) spread spectrum
communication systems.
Research in the area of control theory includes design of robust controllers for complex
systems. Singular perturbation methods are used to develop reduced-order controllers for
continuous-time and discrete-time models, as well as unified models based on the delta
operator. Mixed norm techniques are used to develop robust controllers for large-scale
decentralized systems. Research is also being conducted in networked control systems, time delay systems, spacecraft dynamics and controls, active magnetic bearings, active noise
control, control design, fault detection, and robust filtering.
Research in the area of digital signal processing includes analysis and architecture design of
delta-sigma data converters and speech processing for the hearing impaired. Design of mixed signals integrated circuits, layout, and realization is part of this signal processing effort.
The present work in electromagnetics consists of experimental research into the
electromagnetic (lightning) protection integrity of systems in aging aircraft.
Research in the area of optics includes optical and quantum computing architectures and fiber
optic communications. In optical computing, theoretical and experimental research is being
conducted to realize optical neural computing architectures. In quantum computing,
theoretical work is being performed in realizing computing techniques in very small or
quantum systems. In fiber optics, research is being conducted to exploit the nonlinear
properties of the optical fiber in order to increase date rates.
Research in the area of electric power quality includes power quality troubleshooting, power
system design to better serve loads, disturbance and susceptibility testing of loads, and load
design to decrease disturbances and susceptibility. Power quality research is performed
through the WSU Power Quality Lab, which provides field and laboratory equipment,
computer analysis, and simulation capabilities.
Research in the area of power systems includes development of the Jacobian Matrix for
Power System flow Analysis, Dynamic and Voltage Collapse Stability in Power Systems, and
modeling and simulation of static shunt reactive power compensators for quasi-steady-state
studies.
