Research Achievements

Electromagnetic Interference Issues

Developed analytical models and propose cost effective solutions for electromagnetic interference and electromagnetic compatability (EMI/EMC) and ISR (intelligence, surveillance and reconnaissance) sensors for expanded US Navy E2-C Advanced Hawkeye and EA-6B Prowler missions for Northrop Grumman.

Image Communication

CATT has been deeply involved in addressing technological challenges in the area of image communication, including the issues raised by the introduction of digital video for applications such as high definition television and videoconferencing, as well as issues related to financial document imaging and magnetic resonance medical imaging.

Image Compression

In conjunction with AT&T Bell Laboratories, CATT has developed new methods for motion estimation, a key component in the compression of video sequences. CATT has also developed techniques for image coding and reconstruction that will permit images to be transmitted over packet networks and minimize the degradation caused by the inevitable loss of packets during transmission. Working with doctors at Cornell University Medical College, CATT has developed new techniques for compression of images from magnetic resonance imaging.

Medical Imaging

In a project funded by AFP Imaging Corporation, CATT has developed novel wavelet-based algorithms for the reduction of signal-dependent noise in digital dental x-ray images. The new software has been incorporated in AFP's new generation of filmless digital dental x-ray imaging devices.

Multipath Propagation

Developed space-time-frequency technique to mitigate time-varying multipath propagation effects and HFT transmissions and cellular communications for Fujitsu.

Network Bridging

Because LANs are now so ubiquitous, the ability to bridge them is critical. CATT has conducted extensive research on LAN bridges in cooperation with the Securities Industry Automation Corp. (SIAC), the technology operations center for the New York and American Stock Exchanges. This research enabled SIAC to validate the technically challenging design of the trading floor networks for the exchanges.
