John Cioffi

John M. Cioffi ( born November 7, 1956 in Illinois) is an American electrical engineer, known for his significant contributions to the development of broadband in digital communications technology.

Cioffi studied electrical engineering at the University of Illinois at Urbana -Champaign with a bachelor 's degree in 1978. He continued his studies at Stanford University continued where he in 1979 his master's degree was awarded and has his doctorate in 1984, while at the same time from 1978 to the Bell Laboratories worked. In 1984 he went to IBM where he worked on hard disk read channels. In 1986 he became assistant professor and later professor at Stanford University. Its research on Discrete Tone modulation ( DMT) with his students at Stanford led to DSL technology. In 2009 he retired. Stanford as Hitachi Professor of Engineering

In 1991 he founded Amati Communications Corporation to build DSL modems and marketable. Result was the Prelude modem, which demonstrated the advantages of DSL technology against competing modulation techniques. In 1993 he returned to Stanford, but he remained director of Amati until they were acquired by Texas Instruments in 1998.

He then developed Dynamic Spectrum Management (DSM ) as a development of DSL technology and in 2003 founded Adaptive Spectrum and Signal Alignment Inc. ( ASSIA ), whose CEO and chairman, he is.

2006 Cioffi received the Marconi Prize, in 2001 the IEEE Kobayashi Medal, the 2000 IEEE Third Millennium Award and the 2010 IEEE Alexander Graham Bell Award. He is a member of the National Academy of Engineering ( 2001) and the Royal Society of Engineering ( 2009) and a Fellow of the IEEE (1996). In 2010 he became an honorary doctorate from the University of Edinburgh.
