William C. Lindsey
Biography
William C. Lindsey’s synchronization and communications research has spearheaded the digital communications revolution and created novel technologies for space and mobile wireless communications. Lindsey's work on carrier and clock synchronization methodologies for demodulation and decoder timing significantly improved the performance and efficiency for both data communication and spacecraft tracking and reduced the size, weight, power, and complexity of these devices. Lindsey’s digital-data transaction-tracking loop (DTTL) enabled the decoding of the first photos of Mars from NASA’s Mariner spacecraft as well as images from the Voyager missions, and it was critical to Space Shuttle and space station communications efforts. It also led to the concept of “digital phase-locked systems on a chip” used in modern mobile radios and localization systems.
An IEEE Life Fellow and member of the National Academy of Engineering, Lindsey is a professor of electrical engineering at the University of Southern California, Los Angeles, CA, USA.
