Aaron D. Wyner

Aaron D. Wyner ( born March 17, 1939 in the Bronx, New York, † September 29, 1997 in Morristown ) was an American information theorist.

Wyner graduated from the Bronx High School of Science ( completion in 1955 ) at Queens College of the City University of New York ( bachelor's degree in Mathematics and Physics 1960) and Columbia University, where in 1960 he earned his bachelor's degree in electrical engineering and in 1963 received his doctorate in electrical engineering. Topic of the thesis was the algebraic theory of convolutional codes. After that, he was briefly an assistant professor at Columbia University before moving in 1963 to the Bell Laboratories in Murray Hill, where he since 1974 the Department of Communication Analysis Research conducted (as successor by Stephen O. Rice). From 1993 he was in the Department of Information theory and he was Distinguished Member of the Technical Staff.

1969/70 he was a Guggenheim Fellow at the Weizmann Institute and the Technion. He also taught part-time at Columbia University, Princeton University and the Polytechnic Institute of Brooklyn.

He dealt with coding theory ( channel coding under white noise, algebraic coding, multi-user coding), optical communications processing, cryptography, data compression ( Lempel - Ziv analysis of the algorithm), mobile networks and stochastic processes. In cryptography, its model of the wire -tap channel has been known ( Bell System Technical Journal 1975), that is intercepted communication channels. He showed that it is possible to transmit at a main channel with a sufficiently large capacity compared to listening channel messages to the legitimate receiver, which remain secret from the eavesdropper, as they are hidden in the noise.

Wyner was a member of the National Academy of Engineering ( 1994) and IEEE Fellow. He received the Claude E. Shannon Award. In 1976 he was President of the IEEE Information Theory Society and editor of the IEEE Transactions on Information Theory.

With Neil Sloane he gave the Collected Papers of Claude Shannon out ( IEEE Press, 1993).
