Chris Heegard
9/00 - 9/02 CTO, Home and Wireless Networking, Texas Instruments, Santa
Rosa, California.
1/98 - 9/00 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 exper-
tise 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.
1/89 - now Founder and chief scientist for Native Intelligence, a digital
communications software company.
9/81 - 12/99 Faculty, School of Electrical Engineering, Cornell University.
Taught courses in analog and digital communications, error-correcting coding,
information theory, detection and estimation theory, introduction to digital sys-
tems and audio engineering laboratory: an introduction to audio signal pro-
cessing. Research in the areas of: turbo coding, coded modulation and trellis
group codes, algebraic coding theory and algorithms, applications of symbolic
computation to coding theory, magnetic and optical data recording, sequence
estimation algorithms, analog source coding and data compression, audio and
video signal processing, and information theory. The senior advisor of 18 grad-
uated Ph.D. students.
2/88 - 5/88 Visiting Associate, California Institute of Technology, Pasadena,
California.
9/87 - 5/88 Visiting Scientist, IBM Almaden Research Center, San Jose,
California.
9/78 - 6/81 Research Assistant under the supervision of Professors Thomas
Cover and Abbas El Gamal. Research in a variety of topics in coding, in-
formation 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.
9/76 - 9/78 Research and Development Engineer, Linkabit Corp., 3033 Sci-
ence Park Rd., San Diego, California 92121. This work involved several develop-
ment 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 Link-
abit. A second major area of my involvement was the development of several
sequential decoders for convolutional codes.

Chris Heegard
6/75 - 6/76 Research Assistant under the supervision of Professor Jack K.
Wolf. This research involved the investigation of a coding scheme for the Gaus-
sian broadcast channel.
