signal processing (DSP) lab houses the activities of
several SenSIP faculty. Digital signal processing
emerged as a research area in the 1960s and is now a
mature field enabling a wide range of technologies
including multimedia, entertainment, cellular
communications, automotive and defense applications.
Successful modern products, such as MP3 players and high
definition (HDTV) systems, use sophisticated signal
processing algorithms implemented on DSP chips. Research
in the field includes speech analysis, filter design and
implementation, adaptive filtering, spectral estimation,
time-frequency signal processing, radar and sonar, image
processing and low power signal processing. The faculty
affiliated with the DSP lab include Professors C.
Chakrabarti, D. Cochran, L. Karam, A. Papandreou-
Suppappola and A. Spanias. The group has recently
established a Real-Time Embedded Signal Processing (RESP)
laboratory with support from Motorola, Freescale, Texas
Instruments, National Instruments, and Tektronix.
Theoretical research includes development of new signal
analysis algorithms while experimental and application
research involves real-time system design, software
development, and fast power-aware implementations.

Past Doctoral Graduates
The DSP lab is on the fourth floor of the Goldwater
Center (GWC) and houses several graduate students.
The lab has a network of PC workstations equipped
with a variety of signal processing tools including
MATLAB toolboxes, the National instruments LabVIEW,
numerical recipies and several other mathematical
and signal analysis packages.
