DESCRIPTION/ABSTRACT:

Qualcomm Institute and the Electrical and Computer Engineering Department present the first seminar series on communication theory and systems. Speakers will cover topics in diverse areas, including wireless, optical, location, storage and networking. The goal of this series is to promote the development and use of theory informed by the most recent advancements in the field. Industry speakers, prominent in theory and practice, will share their research and insights each week. This series is unique in that each speaker is expected to spend the day at UC San Diego’s Qualcomm Institute and should be available for meetings and discussions with interested faculty, graduate students, and startups.

The Terabit DSL

This talk reviews an architecture and methodology for ultra-high-speed DSL connectivity.   Known measurements of single-wire copper waveguide modes are extrapolated to a multi-user multiple-input-multiple-output (MU-MIMO) or, equivalently, “Vectored DSL” model for a binder of twisted pairs.  These modes use sub-millimeter- and millimeter-wave frequency bands, and leverage some of the work and exciting positive results in next-generation wireless systems to address coupling and excitation of the waveguide modes.  Projections from these extrapolations have significantly higher speeds than any current DSLs that use the transmission-line method.  Some consideration of practical twisted-pair effects and projected associated complexity are also provided.  This work’s intent is encouragement and motivation of other researchers to further investigate and evaluate these projections.


SPEAKER BIO:

John M. Cioffi – BSEE, 1978,  Illinois; PhDEE,  1984, Stanford;  Bell Laboratories, 1978-1984; IBM Research, 1984-1986; EE Prof., Stanford, 1986-present, now emeritus.

Cioffi founded Amati Com. Corp in 1991 (purchased by TI in 1997) and was officer/director from 1991-1997.  He currently also is on the Board of Directors of ASSIA (Chairman and CEO), Alto Beam, Tinoq, Collinear, and the Marconi Foundation, while serving several advisory boards. Cioffi’s specific interests are in high-performance digital transmission.  Cioffi’s recognition includes: IEEE AG Bell, Kirchmayer, and Millenium Medals (2010, 2014, and 2000); Internet Hall of Fame (2014); Economist Magazine 2010 Innovations Award; International Marconi Fellow (2006); Member, US National and UK Royal Academies of Engineering (2001, 2009); IEEE Kobayashi and Armstrong Awards (2001 and 2013); BBWF Lifetime Achievement (2014), IEEE Fellow (1996); IEE JJ Tomson Medal (2000); 1991 and 2007 IEEE Comm. Mag. best paper; and numerous Conference Best-Paper awards.  Cioffi has published over 600 papers and holds over 100 patents, of which many are heavily licensed including key necessary patents for the international standards in ADSL, VDSL, vectored VDSL, G.fast, DSM, LTE, Massive-MIMO, and various Wi-Fi methodologies.
