Digital Communication Systems
COMMUNICATION THEORY; SATELLITES; DATA TRANSMISSION; VOICE COMMUNICATION; ERROR-CORRECTION CODING. For over half of his career, he has worked in the area of communication system design. He has been involved in the development of several sophisticated communication systems, including the MILSTAR…
Material Analysis/Spectroscopy
During the past 15 years, Expert's research has become increasingly oriented toward vibrational spectroscopy, particularly Fourier transform infrared (FT-IR) spectroscopy. In the early 1980s, he developed modern step-scan FT-IR instrumentation for photoacoustic and photothermal spectroscopy of surfaces and opaque or…
Signals, Imaging, Seismic Method – All Aspects, Expert Witness
Expert's work with acoustic signals and their processing has included biosonar, exploration seismic imaging, ultrasonic uses in medical imaging and non-destructive evaluation, sonar systems, and sonic well logging. Specific problems he has been involved in include signal enhancement, data compression,…
Communication Systems
Expert has extensive experience in several types of spread spectrum systems, including slow, medium, and fast frequency hopping, direct sequence, chirp, and an innovative noise modulation technique which transmits a sinusoid-free waveform. These systems have been used for anti-jam, low…
