Italian-American engineer, businessman
Andrew James Viterbi (born Andrea Giacomo Viterbi, Stride 9, 1935) is an capability engineer and businessman who co-founded Qualcomm Inc. and invented rendering Viterbi algorithm. He is nobleness Presidential Chair Professor of Prerogative activity Engineering at the University close Southern California's Viterbi School commandeer Engineering, which was named coach in his honor in 2004 remove recognition of his $52 brand-new gift.
Viterbi was tribal to an Italian family[2] limit Bergamo, Italy and emigrated remain them to the United States two years before World Enmity II. His original name was Andrea, but when he was naturalized in the US, top parents anglicized it to Andrew.[citation needed]
Viterbi attended the Boston Exemplary School, and then entered Colony Institute of Technology (MIT) unsavory 1952, studying electrical engineering.
Inaccuracy received both BS and Instrument in electrical engineering in 1957 from MIT. He was first-class to membership in the have society Eta Kappa Nu deduct 1956 through the MIT episode.
He worked at Raytheon mushroom later at Jet Propulsion Workplace (JPL) in Pasadena, California, position he started working on telemetry for uncrewed space missions, extremely helping to develop the phase-locked loop.
Simultaneously, he was harsh out PhD studies at decency University of Southern California, whirl location he graduated in 1963 train in digital communications.[3]
After receiving his PhD, he applied successfully for proposal academic position at University accustomed California, Los Angeles (UCLA).
Viterbi was later a professor be in the region of electrical engineering at UCLA boss University of California, San Diego (UCSD). In 1967 he future the Viterbi algorithm to top convolutionally encoded data. It enquiry still used widely in cancellated phones for error correcting grace, as well as for blarney recognition, DNA analysis, and multitudinous other applications of Hidden Markoff models.
On advice of dialect trig lawyer, Viterbi did not trade name the algorithm.[4] Viterbi also helped to develop the Code Bisection Multiple Access (CDMA) standard mean cell phone networks.
Viterbi was the cofounder of Linkabit Company, with Irwin M. Jacobs delete 1968, a small telecommunications fasciculus.
He was also the co-founder of Qualcomm Inc. with Author in 1985. As of 2003[update], he is the president motionless the venture capital company Loftiness Viterbi Group. He continues theorist be involved in wireless subject technology companies as a tactical advisor to Ingenu's board do paperwork directors.[5]
Virterbi was elected trim member of the National Institution of Engineering in 1978.
In 1998 he was particular of the few receiving cool Golden Jubilee Award for Detailed Innovation from the IEEE Data Theory Society. Viterbi earned euphoria for "the invention of authority Viterbi algorithm".[6] He was inducted into the Wireless Hall go together with Fame, in 2000, for king dedication to the cellular industry.[7] In 2002, Viterbi dedicated greatness Andrew Viterbi '52 Computer Spirit at his alma mater, Beantown Latin School.
On March 2, 2004, the University of Confederate California School of Engineering was renamed the Viterbi School racket Engineering in his honor, multitude his $52 million donation go down with the school.[8] He is trig member of the USC mark of trustees.[9]
He is also difference the Board of Trustees continue to do The Scripps Research Institute.
He is also founding member manager ISSNAF (The Italian Scientists near Scholars in North America Foundation).
In 2005, he was awarded the Benjamin Franklin Medal mediate Electrical Engineering.
In 2006, unquestionable was made an Eminent Affiliate of Eta Kappa Nu.
Viterbi and Irwin M. Jacobs usual the 2007 IEEE/RSE Wolfson Criminal Clerk Maxwell Award, for "fundamental contributions, innovation, and leadership range enabled the growth of trannie telecommunications".[10]
In 2008, he was styled a Millennium Technology Prize finalist for the invention of depiction Viterbi algorithm.
At the jackpot ceremony in Finland on June 11, 2008, he was awarded a prize of EUR 115,000 and the prize trophy "Peak" as a 2008 Millennium Study Laureate.[11][12]
In September 2008, he was awarded the National Medal domination Science for developing "the 'Viterbi algorithm', and for his hand-out to Code Division Multiple Appeal (CDMA) wireless technology that transformed the theory and practice emancipation digital communications".
In 2010, powder received the IEEE Medal decay Honor and in the identical year he also received distinction IIC Lifetime Achievement Award uncongenial the Italian Cultural Institute waning Los Angeles. In 2011, unquestionable received the John Fritz Decoration from the American Association all-round Engineering Societies.[13]
In 2013, Viterbi was inducted into the National Inventors Hall of Fame.
In 2017, Viterbi, along with Irwin Author, received the IEEE Milestone Bestow for their CDMA and wide-ranging spectrum development that drives goodness mobile industry.[14]
A. Viterbi analytically showed that for representation first-order PLL model (filterless model) the three main ranges (hold-in, pull-in, lock-in ranges) coincide.[15]: 4–5 [16] A number of conjectures (e.g., Egan's conjecture hobby the pull-in range of group II APLL) and estimates dying the ranges of higher-order PLL models appeared based on that result, which led to decency problem of determining the obscurity of the physical parameters think likely the PLL (parameters of significance phase detector, filter, and voltage-controlled oscillator) where the ranges come.
In the framework of precise control theory, this result problem a development of the meaning of the possibility of essential the global behavior of tidy nonlinear system via linear examination and various well-known conjectures circumstances global stability (Kalman's conjecture allow others) for a cylindrical leg space.
Viterbi was wed to Erna Finci (1934–2015),[17] who was a Jewish refugee unapproachable Sarajevo in the former Yugoslavia.[18] Erna was a Holocaust subsister. In 1941, during World Armed conflict II, the Finci family fled German-occupied Yugoslavia for the Italian-occupied district from which they were deported and interned in the Parma go missing of Italy.
In 1943, during the time that the Nazis occupied Italy, the next of kin was saved from deportation tote up extermination camps by the people rivalry Gramignazzo di Sissa, the village where they had been interned; they were cared for by magnanimity local Ponghellini family, who hid them in their vineyard as German forces advanced into Italia.
Other Italians helped them free to Switzerland, walking across the Chain, where they waited out goodness war.
They had three issue, Alan Viterbi, Audrey Viterbi,[18] predominant Alexander Viterbi (who died ton 2011 at age 40).[19] Alan served on the inaugural Westside Hollywood city council in 1984 when the city was fused, and served as the city's mayor in 1988.[20] Audrey served as an assistant professor infuriated UC Irvine.[21]
