About DBpedia

Aaron D. Wyner (March 17, 1939 – September 29, 1997) was an American information theorist noted for his contributions in coding theory, particularly the Gaussian channel. He lived in South Orange, New Jersey. Wyner was born in the Bronx, New York. In 1955, he graduated from the Bronx High School of Science, and in 1960 completed a five-year joint engineering program with Queens College of the City University of New York and Columbia University. In 1963 he received his Ph.D. in electrical engineering from Columbia University for a thesis that worked out the algebra for convolutional codes.

dbo:abstract Aaron D. Wyner (* 17. März 1939 in der Bronx, New York; † 29. September 1997 in Morristown) war ein US-amerikanischer Informationstheoretiker. Wyner studierte an der Bronx High School of Science (Abschluss 1955), am Queens College der City University of New York (Bachelor-Abschluss in Mathematik und Physik 1960) sowie der Columbia University, an der er 1960 seinen Bachelor-Abschluss in Elektrotechnik erwarb und 1963 in Elektrotechnik promoviert wurde. Thema der Dissertation war die algebraische Theorie von Faltungscodes. Danach war er kurz Assistant Professor an der Columbia University, bevor er 1963 an die Bell Laboratories in Murray Hill ging, bei denen er ab 1974 die Abteilung Kommunikationsanalyse-Forschung leitete (als Nachfolger von Stephen O. Rice). Ab 1993 war er in der Abteilung Informationstheorie und er wurde Distinguished Member of the Technical Staff. 1969/70 war er als Guggenheim-Stipendiat am Weizmann-Institut und am Technion. Er lehrte auch in Teilzeit an der Columbia University, der Princeton University und dem Polytechnikum von Brooklyn. Er befasste sich mit Kodierungstheorie (Kanalkodierung unter Weißem Rauschen, algebraische Kodierung, Mehrbenutzer-Kodierung), optischer Nachrichtenverarbeitung, Kryptographie, Datenkompression (Analyse des Ziv-Lempel Algorithmus), Mobilfunknetzen und stochastischen Prozessen. In der Kryptographie wurde sein Modell des wire-tap channel (Bell System Technical Journal 1975) bekannt, das heißt abgehörter Kommunikationskanäle. Er zeigte, dass es möglich ist bei einem Hauptkanal mit ausreichend großer Kapazität im Vergleich zum Abhörkanal Nachrichten an den legitimen Empfänger zu übertragen, die gegenüber dem Abhörer geheim bleiben, da sie im Rauschen versteckt sind. Wyner war Mitglied der National Academy of Engineering (1994) und IEEE Fellow. Er erhielt den Claude E. Shannon Award. Er war 1976 Präsident der IEEE Information Theory Society und Herausgeber der IEEE Transactions on Information Theory. Mit Neil Sloane gab er die Gesammelten Aufsätze von Claude Shannon heraus (IEEE Press 1993). (de) Aaron D.

Watson Research Center, Wyner joined Bell Laboratories at Murray Hill, New Jersey, as a member of the technical staff. In 1974 he became head of its Communications Analysis Research Department and led it until 1993, when he became a researcher in the information theory department. His research included coding theory, optical communications, cryptography, and stochastic process. In a 1975 paper, he introduced the "wire-tap channel", showing how one could obtain "perfect secrecy" when a receiver enjoys a better channel than does the wire-tapping opponent. Wyner was a member of the National Academy of Engineering, an IEEE Fellow, and received all the IEEE Information Theory Society awards, i.e., the Claude E. Shannon Award, Prize Paper Award, and designation as Shannon Lecturer. (en)
