David Forney

from Wikipedia, the free encyclopedia

George David "Dave" Forney Junior (born March 6, 1940 in New York City ) is an American information theorist , especially known for contributions to coding theory .

Life

David Forney studied electrical engineering at Princeton University with a bachelor's degree in 1961 and at the Massachusetts Institute of Technology with a master's degree in 1963 and a doctorate in 1965. He then worked for Codex Corporation in Newton , where he was vice president for from 1970 to 1975 Research and from 1975 to 1979 for research and development. Codex pioneered high-speed digital modems in the early 1970s. When Codex was taken over by Motorola (1977), he became Vice President (Technical Staff) there in 1980 and Vice President and Director of Technology and Planning from 1982 to 1986.

In 1971/72 and 1990 he was visiting scholar at Stanford University and in the 1990s visiting professor at MIT.

In his dissertation in the 1960s, he introduced concatenated codes , error-correcting codes made up of an inner and an outer code whose decoding complexity increases polynomially with block length with an exponentially decreasing error probability. They were used in space missions from the 1970s. Forney recognized the importance of the Viterbi algorithm early on .

In 1995 he was awarded the Claude E. Shannon Award , the 1997 Marconi Prize , 1992 IEEE Edison Medal , 1984, the Centennial Medal of the IEEE and the 1998 Golden Jubilee Award of the IEEE Information Theory Society . He is a member of the National Academy of Sciences (2003), the American Academy of Arts and Sciences (1998), the National Academy of Engineering (1983) and the American Association for the Advancement of Science as well as an IEEE Fellow (1973). In 2007 he received an honorary doctorate from the École Polytechnique Fédérale de Lausanne (EPFL). For 2016 he was awarded the IEEE Medal of Honor .
