Awarded the Marconi Prize in 1996
"For the invention of Trellis Coded Modulation"
Presented by: HRH Princess Alexandra, The Honorable Lady Ogilvy, at the Victoria and Albert Museum
Dr. Ungerboeck's Trellis Coded Modulation creates an optimal way to encode the ones and zeros in analog waveforms to allow the maximum amount of data to be transmitted over an analog telephone line by minimizing small noise induced distortions. Dr. Ungerboeck is currently at IBM's Zurich Research Laboratory, Switzerland.
