Stella Batalama: Communication Systems and Adaptive Signal Processing
  • Research in wireless communications systems.
Adly Fam: Digital signal processing
  • Dr. Fam's research focuses on digital signal processing. He and his student developed the interlaced chirp Z transform method. This is a new approach towards achieving non-uniform resolution in the frequency domain. The approach is based on using multiple Chirp Z Transforms which are of different resolution and carefully staggered to avoid overlapping of samples. This method proves to be computationally more efficient than other existing non-uniform frequency resolution methods.
Donald Givone: Digital switching
  • Dr. Givone is an expert in switching circuit theory, automata theory, and digital systems. He is the author of an internationally recognized textboot, "Digital Principles and Design."
Raj Kaul: System modeling using engineering mathematics
  • Dr. Kaul is interested in fractal phenomena, wave propagation in periodic structures, wavelets, elasticity and piezoelectricity. He and his students model these systems using engineering mathematics.
Tommaso Melodia: Wireless Networks and Embedded Systems
  • The Wireless Networks and Embedded Systems (WNES) Laboratory was founded in 2007 within the Department of Electrical Engineering, and currently includes three Ph.D. and several M.S. students conducting leading-edge research in wireless networking and communications, embedded systems, and network optimization and control. Current funding sources include the University at Buffalo and the US Air Force Research Laboratory. The laboratory has recognized expertise in the design, modeling, optimization, simulation, and deployment of wireless sensor networks, and in experimental development and measurement. In particular, ongoing research projects include underwater acoustic networking, cognitive radio networks, and wireless multimedia sensor and actor networks.
Dimitrios Pados: Wireless Communications Systems
  • Research in Wireless communications systems.
Mehrdad Soumekh:Synthetic radar imaging
  • Dr. Soumekh is an expert in radar and medical image processing. He is especially recognized for his work in analyzing synthetic radar images. He is funded by the AFOSR. He is the Director of the SAR High Performance Computing Laboratory. The objective of this laboratory is to develop high-speed signal processing and image formation algorithms for Synthetic Aperture Radar (SAR) systems. Under the sponsorship of the Air Force Office of Scientific Research, a High Performance Computing (HPC) laboratory is established for analyzing the merits of various advanced SAR data collection and information processing algorithms such as Continuous Phase Modulation (CPM) chirp radar signaling and PRF staggering schemes for Electronic Counter Counter-Measure (ECCM), along-track monopulse SAR for Moving Target Detection (MTD), rejection of Radio Frequency Interference (RFI) in FOliage PENetrating (FOPEN) SAR, alias-free processing of wide-beamwidth FOPEN SAR data, reconnaissance with Circular SAR (CSAR), and parallel architectures for near real-time image formation (Range Stacking) in FOPEN and Ground PENetrating (GPEN) SAR systems.
  • The SAR HPC laboratory is intended to establish the means by which the collaborative efforts between Dr. Soumekh and the Air Force and Navy laboratories are continued. It is anticipated that this collaboration would not only enhance the quality of research-related education at University at Buffalo but also would yield results which are of significance to the research programs of the Department of Defense.
Weifeng Su: Wireless communications and networks
  • Dr. Su is conducting research in several interesting areas including:
    • Space-Time (ST) Modulation and Coding for MIMO Wireless Communications
    • Space-Frequency (SF) Coding for MIMO-OFDM Systems in Boradband Wireless Communications
    • Cooperative Communications in Mobile Ad Hoc Networks (MANETs)
    • Cross-Layer Design and Optimization for Wireless Networks
    • Ultra-Wideband (UWB) Wireless Communications
    • MIMO Optical Wireless Communications
    • Wavelet Analysis and Filter Banks
