CEO and Principal Scientist, Alantro Communications, Inc. Santa Rosa
California.
Alantro Communications was a fabless semiconductor company
specializing in physical-layer
communications with a particular expertise in
forward error correction (FEC).
The technology is vital in:
high-speed wireless local area networking (IEEE 802.11/WiFi),
cable modems, digital-tv,
digital subscriber line
and
satellite & terrestrial wireless.
Faculty, School of Electrical Engineering, Cornell University.

The senior advisor of 18 graduated Ph.D. students.
Research Assistant under the supervision of Professors Thomas Cover and
Abbas El Gamal.
Research in a variety of topics in coding, information theory and statistics.
Ph.D. thesis titled,
Capacity and Coding for Computer Memory with Defects.
This work answers questions concerning the capacity of defective computer
memory and the description of algebraic error-correcting codes
for combating defects.
Research and Development Engineer, Linkabit Corp., 3033 Science Park Rd., San
Diego, California 92121. This work involved several development projects
related to satellite communications. One major project was the computer
simulation and hardware implementation of a packet satellite PSK modem.
The major demodulation algorithms were performed via a bipolar
microprocessor with a microprogram architecture.
This modem connects the ARPANET to Europe and
formed the basis of a commercial product for Linkabit.
A second major area of my
involvement was the development of several sequential
decoders for convolutional codes.
Research Assistant under the supervision of Professor Jack K. Wolf. This
research involved the investigation of a coding scheme
for the Gaussian broadcast channel.
